Award Amount: $49,777.00
 

Abstract:

THE EFFICIENCIES OF THERMOELECTRIC DEVICES ARE GENERALLY LIMITED BY THE PROPERTIES OF THE AVAILABLE MATERIALS. THE RESEARCHERS PROPOSE TO USE ION BEAM MODIFICATION TO PRODUCE IMPROVED THERMOELECTRIC MATERIALS. BY INTRODUCING DEFECTS AND/OR ALLOYING ELEMENTS BY ION IMPLANTATION, THEY WILL ATTEMPT TO LOWER THE THERMAL CONDUCTIVITY OF THE MATERIALS WITHOUT REDUCING THE SEEBECK COEFFICIENT OR THE ELECTRICAL CONDUCTIVITY, THUS RESULTING IN A HIGHER FIGURE OF MERIT AND MAKING POSSIBLE A HIGHER EFFICIENCY IN THERMOELECTRIC GENERATORS, COOLERS, ETC. IN PHASE I THEY WILL DEPOSIT SI-GE ALLOYS IN THIN FILM FORM, DOPE THEM BY ION IMPLANTATION, AND MEASURE THE RELEVANT ELECTRICAL PROPERTIES.
