This book was released on 2004-02-06 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last research frontier in high frequency electronics lies in the so-called terahertz (or submillimeter wave) regime, between the traditional microwave and the infrared domains. Significant scientific and technical challenges within the terahertz (THz) frequency regime have recently motivated an array of new research activities. During the last few years, major research programs have emerged that are focused on advancing the state of the art in THz frequency electronic technology and on investigating novel applications of THz frequency sensing. This book provides a detailed review of the new THz frequency technological developments that are emerging across a wide spectrum of sensing and technology areas.Volume II presents cutting edge results in two primary areas: (1) research that is attempting to establish THz-frequency sensing as a new characterization tool for chemical, biological and semiconductor materials, and (2) theoretical and experimental efforts to define new device concepts within the “THz gap”.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrafast spectroscopies on the femtosecond timescale are well suited to study electronic dynamics and coupling between quasiparticles in condensed matter systems. These interactions are of great fundamental importance and have widespread applications in engineering. Future developments in spintronics, valleytronics, and optoelectronics depend on an understanding of the couplings of electrons, phonons, magnons, and plasmons. Quasiparticle interactions take place on ultrafast timescales and can be investigated at visible and far infrared wavelengths. This work describes the development and application of time- and frequency-resolved spectroscopies to several important systems, with the purpose of directly detecting the specific quasiparticles involved in the dynamics and determining the timescales of their interactions. First, transient absorption spectroscopy and pump-degenerate four-wave mixing are utilized together to observe the electron-phonon and phonon-phonon scattering in transition metal dichalcogenides. These two spectroscopies jointly identify the specific phonons involved in these interactions. The application of pump-dlegenerate four-wave mixing to a solid state material is novel and requires an in-depth discussion of the interpretation of the measurement. Second, a time-resolved and time-domain terahertz spectroscopy instrument is developed. The characterization of the system is provided and two individual studies show its capabilities. Magnon excitations in single crystal NiO are first measured with terahertz absorption spectroscopy. The determination of these magnon frequencies demonstrates the high frequency resolution of the instrument. Following the magnon study, the charge carrier lifetimes in GaAs and ErAs:GaAs heterostructures are measured with optical pump-terahertz probe spectroscopy. The instrumentation and models of the ultrafast dynamics provide a framework for studying quasiparticle interactions in solid state systems with these techniques.

Download or read book Graphene-Based Terahertz Electronics and Plasmonics written by Vladimir Mitin and published by CRC Press. This book was released on 2020-11-23 with total page 917 pages. Available in PDF, EPUB and Kindle. Book excerpt: Graphene demonstrates interesting electrical, optical, and optoelectronic properties. A number of other one-atom-thick material structures have been discovered and studied. Industrially applicable technologies for these structures are currently under active development. In spite of enormous research in the area of devices based on graphene, the number of extensive review publications on THz devices based on graphene is small. This review volume would fill the gap. Researchers and engineers working in the fields of electronics and plasmonics can use it to understand the influence of plasmonics on device performance. The book can be also be used as a required text for doctorate courses and as a supplementary material for postgraduate courses. The material presented in the book is reviewed in detail in Chapter 1. Chapter 2 discusses the electronic and plasmonic properties of graphene and heterostructures based on graphene for all devices. Chapters 3–7 focus on the concepts of detectors and emitters with a special emphasis on plasmonic enhancement of those devices as well as on population inversion and lasing.

This book was released on 2014-03-10 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reader will find here a timely update on new THz sources and detection schemes as well as concrete applications to the detection of Explosives and CBRN. Included is a method to identify hidden RDX-based explosives (pure and plastic ones) in the frequency domain study by Fourier Transformation, which has been complemented by the demonstration of improvement of the quality of the images captured commercially available THz passive cameras. The presented examples show large potential for the detection of small hidden objects at long distances (6-10 m). Complementing the results in the short-wavelength range, laser spectroscopy with a mid-infrared, room temperature, continuous wave, DFB laser diode and high performance DFB QCL have been demonstrated to offer excellent enabling sensor technologies for environmental monitoring, medical diagnostics, industrial and security applications. From the new source point of view a number of systems have been presented - From superconductors to semiconductors, e.g. Detection of Terahertz Waves from Superconducting Bi2Sr2CaCu2O8+δ Intrinsic Josephson Junctions. The quest for a compact room temperature THz source and the recent advances in high power mid-IR QCLs lead to the development of a semiconductor THz source based on intracavity difference frequency generation. Furthermore, alternative electrically pumped THz sources based on the high emission efficiency predicted for polaritonic states in the ultra-strong coupling regime led to the demonstration of electroluminescent devices. Finally, antipolaritons in dispersive media were discussed and different aspects of the interaction of THz radiation with biomatter were presented.

Available in PDF, EPUB and Kindle. Book excerpt: Intense Terahertz Excitation of Semiconductors presents the first comprehensive treatment of high-power terahertz applications to semiconductors and low-dimensional semiconductor structures. Terahertz properties of semiconductors are in the center of scientific activities because of the need of high-speed electronics. This research monograph brigdes the gap between microwave physics and photonics. It focuses on a core topic of semiconductor physics providing a full description of the state of the art of the field. _ The reader is introduced to new physical phenomena which occur in the terahertz frequency range at the transition from semi-classical physics with a classical field amplitude to the fully quantized limit with photons. The book covers a wide range of optical, optoelectronic, and nonlinear transport processes, presenting experimental results, clearly visualizing models and basic theories. Background information for future work and exhaustive references of current literature are given. A particularly valuable feature is through the discussion of various technical aspects of the terahertz range like the generation of high-power coherent radiation, optical components, instrumentation, and detection schemes of short intense radiation impulses. The book complements, for the first time in form of a monograph, previous books on infrared physics which dealt with low-power optical and opto-electronic processes. It will be useful not only to scientists but also to advanced students who are interested in terahertz research.
