Abstract. Dispersion law is studied for high-frequency longitudinal plasma waves in
2DEG (the plane z = 0), separated by thin dielectric layer from half-limited 3DEG. It is
shown that drift of 3DEG provokes for special conditions instability of considered
plasma waves.
Keywords: instability, electron gas, plasma.
