Abstract :
The characteristics of a new compound-semiconductor heterostructure tunneling resonator are analyzed using the time-dependent Schrodinger equation. The device is formed by imbedding the usual double-barrier tunneling structure between two additional heterojunctions forming the reflectors of the resonator. Tunable quantum mechanical oscillations in the frequency range from 300 to 600 GHz are observed for typical device parameters. Two potential millimeter-wave device applications are proposed
