Abstract

In this paper, a theoretical model calculating the electron escape time form a biased quantum well is presented. To solve Schroedinger equation for a quantum well under the influence of an electric field, the method of the logarithmic derivative of the wave function is used in the Green's function approach. Electron escape time is calculated by accounting for the partitioning of the total current into the thermionic emission and tunneling components. The current components are evaluated by properly accounting for the electron's group velocity and the redistribution of the density of states in the presence of an applied electric field. A comparison between this model and previously reported experimental results of the electron escape time is made, demonstrating excellent agreement.
