Аннотация:A review is given of the up-to-date concepts of electrochemical processes. Electrochemical reactions induced by laser heating in absorbing liquid electrolytes are considered. It is experimentally shown that electric fields and currents are generated in an electrolyte exposed to laser radiation, which is due to the thermal diffusion of absorbing ions. The feasibility of selective deposition of a given element from the solution of its salt under laser radiation is demonstrated. Experimental findings on electrochemical reactions with semiconductors (Si, GaAs, Ge) are presented.
