PAM-XIAMEN can offer 2&3 inches P-type GaAs substrates. Gallium arsenide (GaAs) is a III-V type direct band gap semiconductor with a zinc blend crystal structure, and GaAs p-type dopant is commonly used as a substrate for epitaxial growth of other III-V semiconductors, including indium gallium arsenide, aluminum gallium [...]

We present a numerical study of the electronic and optical properties of a model single-element superlattice made of a periodic sequence of relaxed and strained regions of a germanium crystal, realized by means of an externally applied strain. We adopt the tight-binding model to [...]

Effects of post-growth annealing on the performance of CdZnTe:In radiation detectors with different thickness
An effective post-growth annealing method was used to improve the performance of CdZnTe:In (CZT:In) radiation detectors. The results indicated that Te inclusions in CZT:In crystals with different thickness were eliminated completely [...]
We quantified the size and concentration of Te inclusions along the lateral- and the growth-directions of a ∼6 mm-thick wafer cut axially along the center of a CdZnTe ingot. We fabricated devices, selecting samples from the center slice outward in both directions, and then [...]
