Book Synopsis Properties of Aluminium Gallium Arsenide by : Sadao Adachi
Download or read book Properties of Aluminium Gallium Arsenide written by Sadao Adachi. This book was released on 1993. Available in PDF, EPUB and Kindle. Book excerpt: The alloy system A1GaAs/GaAs is potentially of great importance for many high-speed electronics and optoelectronic devices, because the lattice parameter difference GaAs and A1GaAs is very small, which promises an insignificant concentration of undesirable interface states. Thanks to this prominent feature, a number of interesting properties and phenomena, such as high-mobility low-dimensional carrier gases, resonant tunnelling and fractional quantum Hall effect, have been found in the A1GaAs/GaAs heterostructure system. New devices, such as modulation-doped FETs, heterojunction bipolar transistors, resonant tunnelling transistors, quantum-well lasers, and other photonic and quantum-effect devices, have also been developed recently using this material system. These areas are recognized as not being the most interesting and active fields in semiconductor physics and device engineering.

Book Synopsis Design and Optical Characterization of Gallium Arsenide Aluminum Arsenide Material System Reflective Modulators for Mid-infrared Free Space Optical Applications Using Solid-source Molecular Beam Epitaxy by : Stanley Ikpe
Download or read book Design and Optical Characterization of Gallium Arsenide Aluminum Arsenide Material System Reflective Modulators for Mid-infrared Free Space Optical Applications Using Solid-source Molecular Beam Epitaxy written by Stanley Ikpe. This book was released on 2013. Available in PDF, EPUB and Kindle. Book excerpt: With the ever-growing usage of free space optical communication implementations, new innovations are currently being made to help improve the quality of transmission of these systems. One particular method employed to help improve transmission efficiency of optical links is shifting the transmission wavelength into the mid-infrared spectrum. Studies have shown sufficient increase in atmospheric transmission at and around mid-infrared wavelengths (near 3-5 mm). In order to successfully implement such systems at these wavelengths, devices must first be designed that are capable of optical communication operation at such wavelengths. One such device common in modern free space optical systems is the reflective modulator. This device minimizes the pointing and tracking associated with establishing free space optical connections. In this dissertation, a free space optical reflective modulator is designed using Gallium Arsenide and Aluminum Arsenide (GaAs/AlAs) to operate at midinfrared transmission wavelengths. The reflective modulator consists of multiple quantum well modulator (QWM) atop of a distributed Bragg reflector (DBR). The physical device characteristics are analyzed and the device functionality evaluated using optical characterization techniques.
