✦ Synopsis

Theoretical study of resonant tunneling is carried out in rectangular triple-barrier structures with C-type deep wells. Analytical expressions for the transmission coefficient and the resonance conditions are derived. Transmission characteristics versus electron energy are investigated and it is shown analytically that the transmission spectrum is a Lorentzian in form near energies of resonance. It is confirmed that the resonance energy is almost equal to the eigenenergy of the double-well structure. Moreover, wave functions of an electron at the resonance level are examined and the confining phenomenon is studied.

Resonant tunneling is studied theoretically in symetrical rectangular quadruple-barrier structures. Analytical expressions for the transmission coefficient and the resonance condition are derived. Two independent resonance conditions are obtained especially for structures with four identical rectang
