Abstract
A study was made of the effect of the simultaneous doping with donor (Te) and acceptor (Cu, Ag, Au) elements on the thermoelectric properties of CdSb. Doping with tellurium changes the p-type conductivity of the CdSb crystals to an n-type conductivity with an impurity (Te) activation energy of ΔEd = (0. 11 ± 0. 01) eV. Doping with an acceptor impurity changes the energy of the donor level, by ΔEd = 0. 14 eV for doping with silver, by ΔEd = 0. 10 eV for doping with gold and by ΔEd = 0. 095 eV for doping with copper. It is shown that the type of conductivity and the thermoelectric properties of CdSb can be adjusted in the desired direction through simultaneous doping with two impurities.
