We have developed a 256×256-element HgCdTe hybrid infrared focal plane array for 8-10μm band that is both large scale and highly sensitive. Three new techniques were used to achieve the large scale array. First, a thin silicon readout circuit on a

HgCdTe epilayers were grown on CdZnTe substrates by molecular beam epitaxy, and the substrate orientation influence on growth defects was investigated. In the HgCdTe( 111 )B epilayers, many “lamellar” and/or “columnar” twins were observed, wh

The effects of mercury partial pressure on the defect density in HgTe grown by metalorganic chemical vapor deposition (MOCVD) have been investigated. A large number of mercury clusters were revealed by transmission electron microscopy in high mercury

We have systematically studied the growth conditions of Cd 0.22 Hg 0.78 Te liquid-phase epitaxy using an open-tube horizontal slider apparatus. Optimizing each parameter, we have reproducibly obtained high-quality p-Cd 0.22 Hg 0.78 Te epitaxial layer

Hg 1− x Cd x Te layers grown by molecular beam epitaxy (MBE) often show anomalous electrical conduction when the Hall effect is measured. This behavior can definitely be eliminated and changed to a uniform p-type conduction, when the layers are ann

Cd compositions of HgCdTe epilayers and photodiodes were estimated, respectively, by measuring infrared transmission curves at 300 K and spectral response curves at 77 K, along with using an empirical formula on energy band gap for HgCdTe. Comparing

There are two growth methods in Hg1−xCdxTe metalorganic chemical vapor deposition (MOCVD) growth, namely direct alloy growth (DAG) and the interdiffused multilayer process (IMP). HgCdTe layers have been grown by both methods onto CdZnTe (111)B subs
