Abstract:   (5950 Views)
In this article, tunneling resonance (transmission coefficient, current density and negative differential resistance) has been studied for Alx Ga1-x As / GaAs triangular double quantum wells. Time dependent Schrodinger equation has been used for triangular quantum wells structures accompanied with Airy function. Transmission and reflection coefficients before and after applying external electrical field were obtained for two symmetrical triangular quantum well in terms of effective mass approximation as a function of structural  parameters such as well width, barrier width, well depth and applied voltage. Results showed a negative differential resistance at this kind of quantum wells.
