Plasma wave effect describes the influence of diffusion and irradiative recombination processes of excess carriers on the instantaneous temperature distribution in the sample. This temperature field is responsible for a series of effects observed experimentally. The most important element for the computations of the plasma wave effect is the formula for the spatial temperature distribution in the sample. The aim of this paper was: to investigate and compare different temperature distribution formulae, derive another temperature distribution formula with the thermal wave interference method of Benett and Patty and simplify the notations to make the formula more convenient and practical.
