Abstract

Using the pyroelectric method (TSWM), it was shown that the heat-conduction and thermal diffusivity coefficients of p-type germanium single crystals depend on the doping concentration of Ga (1 × 1014, 3 × 1014, 4.5 × 1014, 9 × 1014, 3.5 × 1015 cm–3) in the [111], [110] and [100] crystallographic orientation. It is found that the error in determining the thermal diffusivity is not more than 9%, the thermal conductivity‒10%. The measurements were carried out in the temperature range 20–80°С.
