Abstract
THERMOELECTRIC MATERIALS ARE USED IN A VARIETY OF POWER SOURCES AND PELTIER REFRIGERATORS. THEDIMENSIONLESS FIGURE-OF-MERIT (ZT) IS USED AS A MEASURE OF THE RELATIVE EFFECTIVENESS OF THESE MATERIALS. THE BEST KNOWN MATERIALS HAVE ZTS OF LESS THAN ONE. NEW SOLID STATE THEORY PREDICTS THAT MULTILAYER-QUANTUM WELL FILMS COULD HAVE ZTS GREATER THAN SIX. IN PHASE I SUCH MATERIALS WILL BE PRODUCED BY ALTERNATELY DEPOSITING A QUANTUM WELL LAYER OF A THERMOELECTRIC MATERIAL AND A SUITABLE BARRIER LAYER. EVALUATION OF THESE MATERIALS WILL CONSIST OF MEASUREMENT OF SEEBECK COEFFICIENT, RESISTIVITY, AND THERMAL CONDUCTIVITY, AS WELL AS A DIRECT MEASUREMENT OF Z. TRANSMISSILN ELECTRON MICROSCOPY WILL BE USED TO EVALUATE THE OTHER MATERIALCHARACTERISTCS.
