Notizen:
Impurites were tracked from raw material purification through to CdZnTe processing in an effort to identify the sources of elements which impact on IR photodetector performance. Chemical analyses by GDMS and ZCGFAA effectively showed the levels of impurities introduced into CdZnTe substrate material from the manufacturing processes. A new purification process (ISDZR) for raw materials was developed, resulting in improved CdZnTe substrate purity. Substrate CU contamination was found to have detrimental effects on LPE layer and device electrical properties for lightly doped HgCdTe.
