Available in PDF, EPUB and Kindle. Book excerpt: "III-V semiconductors are increasingly used to produce high performance infrared photodetectors; however a significant challenge inherent to working with these materials is presented by unintended electrical conduction pathways that form along their surfaces. Resulting leakage currents contribute to system noise and are fine ectively mitigated by device cooling, and therefore limit ultimate performance. When the mechanism of surface conduction is understood, the unipolar barrier device architecture o ers a potential solution. III-V bulk unipolar barrier detectors that e ectively suppress surface leakage have approached the performance of the best II-VI pn-based structures. This thesis begins with a review of empirically determined Schottky barrier heights and uses this information to present a simple model of semiconductor surface conductivity. The model is validated through measurements of degenerate n-type surface conductivity on InAs pn junctions, and non-degenerate surface conductivity on GaSb pn junctions. It is then extended, along with design principles inspired by the InAs-based nBn detector, to create a flat-band pn-based unipolar barrier detector possessing a conductive surface but free of detrimental surface leakage current. Consideration is then given to the relative success of these and related bulk detectors in suppressing surface leakage when compared to analogous superlattice-based designs, and general limitations of unipolar barriers in suppressing surface leakage are proposed. Finally, refinements to the molecular beam epitaxy crystal growth techniques used to produce InAs-based unipolar barrier heterostructure devices are discussed. Improvements leading to III-V device performance well within an order of magnitude of the state-of-the-art are demonstrated."--Page ix.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photodetectors operating in the mid-infrared wavelength range have traditionally been dominated by the HgCdTe (MCT) material system. However, there has been growing interest in other materials due to environmental concerns regarding the toxicity of both mercury and cadmium, as well as issues with the non-uniformity of MCT epitaxial growth and minimal MCT fabrication infrastructure, compared to that of traditional arsenic- and antimony-based III-V material systems. One such example is the type-II superlattice (T2SL), which has shown great potential due to its theoretically predicted advantages such as suppressed Auger recombination, as well as for its bandgap flexibility. Yet at longer wavelengths, superlattices show weaker absorption coefficients compared to bulk materials. One option to address this deficiency is to utilize optical engineering to overcome the decreased absorption of T2SLs at these wavelengths, leveraging phenomena such as plasmonic structures. Highly doped semiconductors can act as plasmonic materials in the mid-infrared, allowing for monolithic integration of these materials into optoelectronic device structures. In this work, several all-epitaxial structures are discussed, highlighting the capabilities of integrated highly doped semiconductor materials, as well as the potential of T2SLs as an absorber material, for next generation infrared photodetectors. The first example is an all-epitaxial dielectric-metal-dielectric structure capable of supporting long-range surface plasmon polaritons in the long-wave infrared, with type-II superlattices (T2SLs) utilized as the dielectric layers in this structure. Additionally, a thin long-wave infrared p-i-n detector designed for enhanced absorption at band-edge, utilizing a guided mode resonance, is investigated. Furthermore, a detector operating at 180K in the long-wave infrared, utilizing a resonant cavity, and configured for focal plane arrays, is demonstrated. The absorption peak for this detector can be spectrally tuned across the long wave infrared wavelength range by changing the total cavity thickness, and experimental results show an external quantum efficiency of 25% on resonance at 10.8μm. Another possible alternative to the HgCdTe material system is a quaternary alloy such as InAsSbBi, which also offers large design flexibility without a weaker absorption coefficient. The potential of InAsSbBi as an absorber material for infrared detectors is also investigated, through photoluminescence and minority carrier lifetime measurements. Finally, future work and potential new directions for these projects are discussed. In particular, possible methods to improve the optical and electrical characteristics of the resonant cavity enhanced detectors are included

Available in PDF, EPUB and Kindle. Book excerpt: Although elemental semiconductors such as silicon and germanium are standard for energy dispersive spectroscopy in the laboratory, their use for an increasing range of applications is becoming marginalized by their physical limitations, namely the need for ancillary cooling, their modest stopping powers, and radiation intolerance. Compound semiconductors, on the other hand, encompass such a wide range of physical and electronic properties that they have become viable competitors in a number of applications. Compound Semiconductor Radiation Detectors is a consolidated source of information on all aspects of the use of compound semiconductors for radiation detection and measurement. Serious Competitors to Germanium and Silicon Radiation Detectors Wide-gap compound semiconductors offer the ability to operate in a range of hostile thermal and radiation environments while still maintaining sub-keV spectral resolution at X-ray wavelengths. Narrow-gap materials offer the potential of exceeding the spectral resolution of germanium by a factor of three. However, while compound semiconductors are routinely used at infrared and optical wavelengths, their development in other wavebands has been plagued by material and fabrication problems. So far, only a few have evolved sufficiently to produce commercial detection systems. From Crystal Growth to Spectroscopic Performance Bringing together information scattered across many disciplines, this book summarizes the current status of research in compound semiconductor radiation detectors. It examines the properties, growth, and characterization of compound semiconductors as well as the fabrication of radiation sensors, with particular emphasis on the X- and gamma-ray regimes. It explores the limitations of compound semiconductors and discusses current efforts to improve spectral performances, pointing to where future discoveries may lie. A timely resource for the established researcher, this book serves as a comprehensive and illustrated reference on material science, crystal growth, metrology, detector physics, and spectroscopy. It can also be used as a textbook for those new to the field of compound semiconductors and their application to radiation detection and measurement.
