This book was released on 2011 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This thesis is devoted to the optical characterization of Cd1-xMnxTe [(Cd,Mn)Te] semiconductor based radiation detectors. In it I present my research on the study of (Cd,Mn)Te single crystal as both a material for detection of high-energy x rays as well as for sub-picosecond voltage sensing. The work includes the practical implementation of (Cd,Mn)Te, its characterization using ultrafast spectroscopy, and comparative measurements to other competitive materials. Characterization of the voltage sensitivity of (Cd,Mn)Te is accomplished using time-resolved spectroscopy and sub-picosecond electro-magnetic pulses. My research shows that the electro-optic (EO) effect of (Cd,Mn)Te is nearly an order of magnitude greater than previously believed, and accomplishes voltage sensitivities for THz signals greater than traditional EO transducers currently available. For measurements of low-frequency signals, the results agree with the unexceptionally low textbook value; however, through various experiments studying the EO dependence on temperature, fabrication technique, and frequency, I show that the culprit for the low sensitivity at low frequency is free-carrier screening. Furthermore, testing the wavelength dependence shows that the sensitivity is enhanced for optical probe energies approaching the crystal bandgap, which in of itself, is tunable in the visible to near infrared spectrum by changing the manganese concentration. Comparative measurements to LiTaO3 are made showing the same sub-picosecond temporal resolution, but significantly greater voltage sensitivity absent of dielectric loading. I further report on the implementation of (Cd,Mn)Te photoconductive devices (PCDs) as the diagnostics x-ray detection tool used for conducting inertial confinement fusion (ICF) experiments in the OMEGA Facility at the University of Rochester's Laboratory for Laser Energetics, and compare the results to those of standard diamond PCDs. I present measurements of the (Cd,Mn)Te PCDs, intended to characterize both the temporal and spectral dependence of x-ray emissions from laser-illuminated targets during ICF experiments. The Cd0.95Mn0.05Te single crystals, doped with vanadium and annealed in Cd vapor, exhibit resistivity of [...characters removed]. A 1-mm-long and 2.3-mm-long detector is placed in the same housing as a 1-mm-long diamond PCD. Each device is preceded by a Be x-ray filter with 37% x-ray transmission at the 1-keV cutoff energy. The energy of the incident OMEGA laser pulses vary from 2.3 kJ to 28 kJ. Using targets of empty plastic shells, we observe two x-ray emission events separated by 1.24 ns: the first event is caused by heating of the shell that created a hot corona, while the second event is an x-ray emission from the fully compressed target. ICF experiments of targets with steel cores enable the analysis of time-resolved relaxation dynamics of photo-excited carriers in the (Cd,Mn)Te crystals. According to my calculations, the (Cd,Mn)Te material can effectively absorb x rays with energies of up to 200 keV. Thus, the (Cd,Mn)Te PCDs are likely to complement the diamond detectors currently used in the laser-confinement fusion experiments."--Leaves v-vi.

Available in PDF, EPUB and Kindle. Book excerpt: This five-volume handbook focuses on processing techniques, characterization methods, and physical properties of thin films (thin layers of insulating, conducting, or semiconductor material). The editor has composed five separate, thematic volumes on thin films of metals, semimetals, glasses, ceramics, alloys, organics, diamonds, graphites, porous materials, noncrystalline solids, supramolecules, polymers, copolymers, biopolymers, composites, blends, activated carbons, intermetallics, chalcogenides, dyes, pigments, nanostructured materials, biomaterials, inorganic/polymer composites, organoceramics, metallocenes, disordered systems, liquid crystals, quasicrystals, and layered structures. Thin films is a field of the utmost importance in today's materials science, electrical engineering and applied solid state physics; with both research and industrial applications in microelectronics, computer manufacturing, and physical devices. Advanced, high-performance computers, high-definition TV, digital camcorders, sensitive broadband imaging systems, flat-panel displays, robotic systems, and medical electronics and diagnostics are but a few examples of miniaturized device technologies that depend the utilization of thin film materials. The Handbook of Thin Films Materials is a comprehensive reference focusing on processing techniques, characterization methods, and physical properties of these thin film materials.

Available in PDF, EPUB and Kindle. Book excerpt: Numerous applications within the mid- and long-wavelength infrared are driving the search for efficient and cost effective detection technologies in this regime. Theoretical calculations have predicted high performance for InAs/GaSb type-II superlattice structures, which rely on mature growth of III-V semiconductors and offer many levels of freedom in design due to band structure engineering. This work focuses on the fabrication and characterization of type-II superlattice infrared detectors. Standard UV-based photolithography was used combined with chemical wet or dry etching techniques in order to fabricate antinomy-based type-II superlattice infrared detectors. Subsequently, Fourier transform infrared spectroscopy and radiometric techniques were applied for optical characterization in order to obtain a detector's spectrum and response, as well as the overall detectivity in combination with electrical characterization. Temperature dependent electrical characterization was used to extract information about the limiting dark current processes. This work resulted in the first demonstration of an InAs/GaSb type-II superlattice infrared photodetector grown by metalorganic chemical vapor deposition. A peak detectivity of 1.6x10^9 Jones at 78 K was achieved for this device with a 11 micrometer zero cutoff wavelength. Furthermore the interband tunneling detector designed for the mid-wavelength infrared regime was studied. Similar results to those previously published were obtained.

Available in PDF, EPUB and Kindle. Book excerpt: Bringing together contributions from leading experts in the field, this book reviews laser processing concepts that allow the structuring of material beyond optical limits, and methods that facilitate direct observation of the underlying mechanisms by exploring direct structuring and self-organization phenomena. The capacity to nanostructure material using ultrafast lasers lays the groundwork for the next generation of flexible and precise material processing tools. Rapid access to scales of 100 nm and below in two and three dimensions becomes a factor of paramount importance to engineer materials and to design innovative functions. To reflect the dynamic nature of the field at all levels from basic science to applications, the book is divided into three parts, Fundamental Processes, Concepts of Extreme Nanostructuring, and Applications, each of which is comprehensively covered. This book will be a useful resource for graduate students and researchers in laser processing, materials engineering, and nanoscience.
