Resonant Tunneling Properties of Gaussian Double Barrier Potential and Effect of the Electric Field Bias
Abstract
Resonant tunneling properties of finite Gaussian double quantum barrier
structure are studied in the absence and presence of electric field bias. Non-equilibrium
Green's function method based on the finite difference method is used. A
detailed analysis of the resonant energy level is given and the importance of
system parameters is discussed. The dependence of the transmission properties
on the barriers and electric field bias are revealed. A comparison between
different barrier shape data is presented.
