ON THERMOELECTRIC PROPERTIES OF CDXHG1-XSE ALLOYS

The thermal and electrical conductivity, Hall and Seebeck coefficients have been measured as a function of temperature for various undoped alloys up to x=0.50. The Hall coefficient and the thermoelectric power remained negative for all samples at all temperatures in the investigated range (77 to 450° K). The alloys with x=0.10 provided the optimum figure of merit, which reached a maximum of 0.9 × 10-3 deg-1 at 400° K. This represents an improvement of at least 50% over the best values for n-type Ge-Si alloys below 700° K. © 1969 Chapman and Hall.
