The appearance of thermoelectric power on heated p-n heterostructures containing on the surface of silicon substrates the deposited films from a Si-Ge solid solution heavily doped with titanium was experimentally observed. The appearance of the thermoelectric power, even with uniform heating of the samples, had been explained by the thermal-voltaic effect, that is the generation of charge carriers due to the absorption of subband photons with the participation of deep energy levels caused by both structural defects of Si-Ge films and an impurity of titanium. It is shown that when the p-n structures are heated to 800 K, the emf is several mV, and the additional local illumination of the surface leads to an increase in the current by a factor of 15.
