Hydrogenated Amorphous Silicon Photoresists for Hgcdte Patterning
A process to use a hydrogenated amorphous silicon (a-Si:H) film as a dry photoresist mask for plasma etching of HgCdTe has been demonstrated. The a-Si:H films were deposited using standard plasma enhanced chemical vapor deposition with pure silane as the

LWIR HgCdTe: Innovative detectors in an incumbent technology [PDF]
HgCdTe is the current material of choice for high performance imagers operating at relatively high temperatures. Its lack of technological maturity compared with silicon and wide-band gap III-V compounds is more than offset by its outstanding IR ...

HgCdTe MBE Technology: A Focus on Chemical Doping
HgCdTe MBE technology is becoming a mature growth technology for infrared focal plane array applications. The ability to dope HgCdTe with In(n-type) and As(p-type) dopants in-situ provides greater flexibilities for fabricating heterojunction devices.

Bandgap Engineered HgCdTe Nano-Crystal Based Hetero-Junction Infrared Sensor
Advantage of remote-sensing in mid wave infrared (MWIR) spectral range (2 mu m-5 mu m) due to atmospheric transmission window. Dominant photon detectors in this range are single crystal InSb and HgCdTe, while cost of these detectors is very high and ...
