Research abstract
MERCURY CADMIUM TELLURIDE (HGCDTE) IS A PRIMARY LONGWAVE INFRARED SENSOR MATERIAL. RECENTLY, HGZNTE GIVES INDICATIONS OF BEING SUPERIOR DUE TO A MORE STABLE HGTE BOND. HGZNTE HAS BANDGAP ENERGIES, ELECTRICAL AND OPTICAL PROPERTIES SIMILAR TO HGCDTE. THEREFORE, IT COULD BE CONSIDERED FOR ALL PRESENT HGCDTE TASKS. THE DEVELOPMENT OF SOPHISTICATED HGZNTE INFRARED DEVICE STRUCTURES WILL DEPEND ON AVAILABILITY OF COMPLEMENTARY CDZNTE SUBSTRATES FOR LATTICE MATCHED EPITAXIAL GROWTHS. SIMULTANEOUS DEVELOPMENT OF BOTH A CDZNTE SUBSTRATE AND HGZNTE EPITAXY DATA BASE IS PROPOSED IN THIS WORK.
