Query: Effect of carrier heating on photovoltage in FET   We have calculated, within the framework of the Boltzmann equation, a dc
electric current and emf in a two-dimensional system induced by the
high-frequency field of an electromagnetic wave or the electric field of a
plasmon wave. It is established that the generated current consists of two
contributions, one of which is proportional to the real part of the wave vector
projection of the exciting wave onto the interface plane and represents the
electron drag effect, and the other contribution is proportional to the
extinction coefficient of the wave in the interface plane. It is shown that the
main cause of the second contribution is a nonuniform electron heating created
by the wave and controlled by the energy relaxation time of the electron gas.
In FET the heating mechanism of the electric-current formation can remarkably
exceed the current calculated neglecting the heating.
