Diffusion of Zinc in Gallium Arsenide

Macroscopic diffusion models for precipitation in crystalline gallium arsenide

Based on a thermodynamically consistent model for precipitation in gallium arsenide crystals including surface tension and bulk stresses by Dreyer and Duderstadt [DD08], we propose two different mathematical models to describe the size evolution of liquid droplets in a crystalline solid. The first model treats the diffusion-controlled regime of interface motion, while the second model is concer...

Self- and Zinc Diffusion in Gallium Antimonide

Gallium Arsenide - Based Readout Electronics

The readout of detector arrays requires the monolithic or hybrid integration of a integrate circuit multiplexer with the detector array. In most LWIR and VLWIR applications, a hybrid approach is used. For example, the detector array may be built from HgCdTe and the readout integrated circuit may be silicon CMOS [1]. The two integrated circuits are mated through a bump-bonding process in which e...
