| Abstract: | Two modulation techniques were used to determine the heat capacity of 1 mil gold wire as a function of temperature. A frequency effect was observed at high temperature in the directly measured parameter Cp/(1/Rm) (dR/dT)Tm where Cp is the specific heat at constant pressure and Rm is the resistance of the specimen at temperature Tm. It is believed that the vacancy defect is responsible for this frequency effect. The relaxation phenomenon observed suggests the surface of the wire as the source of the vacancies. |
