Аннотация

An expression for the average velocity of a semiconductor photomotor has been obtained. A threelevel model of the electron subsystem of a photomotor with arbitrary transition rate constants was considered, and the time dependences of the occupation of its electronic levels were calculated. Variation of the occupation of the levels with time determines the time dependence of the potential energy and the average velocity of the photomotor motion along the polar substrate. The optimum conditions of laser photoexcitation and the kinetic characteristics of electron transitions in the photomotor that provide the maximum velocity of its directional motion were determined.
