Available in PDF, EPUB and Kindle. Book excerpt: Characterization of Nanostructures by Near-Field Scanning Optical MicroscopyAbstractThis thesis research focuses on applying near-field scanning optical microscopy to characterize designed nanostructures. The near-field imaging concept is based on Synge's idea that a light source with size smaller than the wavelength can scan a sample point-by-point, sequentially probing its optical property. Near-field scanning optical microscopy (NSOM) is a powerful imaging tool since it provides spectral information at nanoscale in correlation with morphological details. This thesis work utilizes a home-built apertureless NSOM for the investigation of designed nanostructures. In this design, NSOM light source was produced by excitation of commercial silicon nitride (Si3N4) AFM probes with an ultraviolet laser, e.g., 405 nm. Such a light source has the intrinsic advantages of stability, durability and high emission intensity. In addition, utilizing bright photoluminescent (PL) probes simplifies the separation and detection of near-field signals because the PL exhibits different wavelength from the far-field excitation beam.In terms of the nanostructures fabrication, a method utilizing particles lithography in sequence in conjunction with surface chemistry was developed to produce multicomponent nanostructures. Multicomponent nanostructures with individual geometry have attracted much attention because of their potential to carry out multifunctions synergistically by all components. A film of monodispersed particles serves as a structural mask to guide the deposition of different materials in a designed sequence. After the particle mask is displaced, multicomponent nanostructures are revealed with well-defined sizes and geometries. Such a method has the advantages of simplicity, a high throughput and the capability of patterning a broad range of materials. By changing the size of the particle template and deposition methods, feature size and geometry of the patterns can be well controlled. Furthermore, only one structural mask is applied during the entire patterning process. This method is straightforward and enables designing and constructing two- and three-dimensional structures tailored with designed functionalities. The aforementioned method can be extended to using different particle masks sequentially. Periodic metal nanostructures of Au and Cu have been produced sequentially using particle lithography, and the overlapped regions serve as Moire patterns at a nanometer scale. NSOM was applied to probe Moire effect directly at the nanometer scale. Moire effect in these regions can be directly visualized from NSOM images, from which periodicity and structural details are accurately determined. In addition, the near-field Moire effect was found to be very sensitive to structural changes, such as lateral displacement and/or rotations of the two basic arrays with respect to each other. Further, nanostructures of Cu exhibited higher photon transmission than Au from NSOM images. Collectively, NSOM enables direct visualization of Moire effect at nanoscale levels from optical read out, and without enhancements or modification of the structures. The results demonstrate the feasibility of extending applications of Moire effect-based techniques to nanometer levels.The same NSOM setup was utilized to investigate the upconversion metal enhancement effect. Rare-earth upconversion particle (RE-UCP) modified AFM probes were successfully fabricated by attaching RE-UCP to the apex of the AFM probe with glue. The optical properties of the probes were investigated. Under illumination of the 980 nm laser, they emit green light, which is consistent with single crystal behavior. The RE-UCP modified AFM probe was utilized as a NSOM probe to investigate the metal enhancement effect. Upon contact, 1.59-fold enhancements in blue peak and 1.63-fold enhancements in red peak are observed. Such a method provides an alternate tool in the study of the metal enhancement effect within complex surface structures.

Book excerpt: Making a clear distinction is made between nano- and micro-mechanical testing for physical reasons, this monograph describes the basics and applications of the supermicroscopies AFM and SNOM, and of the nanomechanical testing on rough and technical natural surfaces in the submicron range down to a lateral resolution of a few nm. New or improved instrumentation, new physical laws and unforeseen new applications in all branches of natural sciences (around physics, chemistry, mineralogy, materials science, biology and medicine) and nanotechnology are covered as well as the sources for pitfalls and errors. It outlines the handling of natural and technical samples in relation to those of flat standard samples and emphasizes new special features. Pitfalls and sources of errors are clearly demonstrated as well as their efficient remedy when going from molecularly flat to rough surfaces. The academic or industrial scientist learns how to apply the principles for tackling their scientific or manufacturing tasks that include roughness far away from standard samples.
Book Synopsis Characterization of Nanostructures by : Sverre Myhra
Download or read book Characterization of Nanostructures written by Sverre Myhra and published by CRC Press. This book was released on 2012-06-12 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: The techniques and methods that can be applied to materials characterization on the microscale are numerous and well-established. Divided into two parts, Characterization of Nanostructures provides thumbnail sketches of the most widely used techniques and methods that apply to nanostructures, and discusses typical applications to single nanoscale objects, as well as to ensembles of such objects. Section I: Techniques and Methods overviews the physical principles of the main techniques and describes those operational modes that are most relevant to nanoscale characterization. It provides sufficient technical detail so that readers and prospective users can gain an appreciation of the strengths and limitations of particular techniques. The section covers both mainstream and less commonly used techniques. Section II: Applications of Techniques to Structures of Different Dimensionalities and Functionalities deals with the methods for materials characterization of generic types of systems, using carefully chosen illustrations from the literature. Each chapter begins with a brief description of the materials and supplies a context for the methods for characterization. The volume concludes with a series of flow charts and brief descriptions of tactical issues. The authors focus on the needs of the research laboratory but also address those of quality control, industrial troubleshooting, and online analysis. Characterization of Nanostructures describes those techniques and their operational modes that are most relevant to nanoscale characterization. It is especially relevant to systems of different dimensionalities and functionalities. The book builds a bridge between generalists, who play vital roles in the post-disciplinary area of nanotechnology, and specialists, who view themselves as more in the context of the discipline.

Book Synopsis Near-field Microscopy in Liquid for Accurate High-resolution Optical Characterization by : Maurice R. Ayache
Download or read book Near-field Microscopy in Liquid for Accurate High-resolution Optical Characterization written by Maurice R. Ayache and published by . This book was released on 2012 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Near-field scanning optical microscopy (NSOM) is a powerful technique which allows deeply subwavelength imaging by placing a nanoscale aperture in close proximity to a sample where it can collect evanescent fields which contain information about subwavelength features. Additionally, by coupling out these evanescent fields, it has the ability to image light propagation within light-confining guided-wave structures. NSOM can be enhanced by integration into the signal arm of a heterodyne interferometer (H-NSOM), which allows imaging of both amplitude and phase at subwavelength resolution. In this dissertation we apply H-NSOM to characterize novel structures, and introduce a new technique for using H-NSOM in a liquid environment. First, we use the H-NSOM to characterize an asymetric mode converter, which uses a one-way wavevector created by a metallic grating. The asymmetric propagation is visualized directly, then verified by using Fourier analysis to examine the mode content of the waveguide fields. Next, we propose and implement a scheme for H-NSOM measurement of silicon integrated waveguides with liquid cladding. Fourier analysis is used to determine an effective index shift of .08 in the quasi-TM mode between air and water overcladdings. This technique is then succesfully applied to directly image long range surface plasmons for the first time. The liquid cladding enables preservation of the symmetric cladding environment required for long range plasmon propagation. We directly observe the field distribution of the single mode, and show that it matches well to simulations.
