Abstract
LOW GROWTH TEMPERATURES ARE ESSENTIAL FOR THE METAL-ORGANIC CHEMICAL VAPOR DEPOSITION (MOCVD) OF ABRUPT HETEROJUNCTION DEVICES FABRICATED FROM MERCURY CADMIUM TELLURIDE. UNSYMMETRICAL TELLURIDES (RTER< >1D) REPRESENT A NOVEL ALTERNATIVE TO THE NON-OPTIMAL SOURCE REAGENTS CURRENTLY IN USE. THESE UNSYMMETRICAL TELLURIDES WILL HAVE INCREASED VOLATILITY WHILE MAINTAINING LABILE TELLURIUM-CARBON BONDS BY APPROPRIATE CHOICE OF THE R AND R< >1D GROUPS. THE GOAL OF THE PROPOSED RESEARCH IS TO SYNTHESIZE AND CHARACTERIZE ASERIES OF FIVE COMPOUNDS OF FORMULA RTER< >1D BY MODIFICATIONS OF LITERATURE PROCEDURES. THESE FIVE COMPOUNDS WILL BE PYROLYZED AND THE PRODUCTS IDENTIFIED. THE RELATIVE ROLE OF CARBON-BASED VS. TELLURIUM-BASED RADICALS ON THE DECOMPOSITION RATE AND GROWTH TEMPERATURE WILL BE STUDIED. SUCCESS IN PHASE I WILL RESULT IN THE IDENTIFICATION OF NEW, LOW TEMPERATURE SOURCE REAGENTS FOR THE MOCVD OF TELLURIUM ALLOYS.
