A negative photoconductivity which can be exploited to control the properties of the quasi-2D electron layer at an InSb/GaAs heterojunction has been discovered. Measurements carried out in electric fields at T— 1.0 К confirm the possibility of an energy relaxation of non-equilibrium electrons among 2D phonons.
