Analysis of resonant tunneling for parabolic double barrier structure

In this paper the resonant tunneling through the double barrier structure with the parabolic quantum well is studied theoretically. The transmission coefficient for such a structure as a function of applied voltage and the current-voltage characteristics' are calculated and compared with those for the double barrier structure with the rectangular quantum well. The conclusion is that the resonant tunneling through parabolic double barrier structure can be used as a method of determination of the conduction band offset of the barrier and the well materials.
