Influence of the Space Charge on Tunneling of Electrons and Their Conductivity by the Resonance Tunneling Structures in the Constant Electric Field

Abstract

The quantum mechanical theory of spectral parameters and dynamic conductivity of electrons, interacting with field of the created by them space charge in open flat resonance tunneling structure with a constant electric field in the model of rectangular potential wells and barriers has been developed. The influence of space charge on the conductivity of the experimentally realized nanostructures as the active region of a quantum cascade laser for different concentrations of electrons in the falling on the resonance tunneling structure beam, has been investigated.

Model of nanoporous medium with charged impurities

“…It should be noticed that at present there is actually no papers where mass transfer models were modified in order to describe investigated processes more clearly. Related problems concerning the influence of space charge on mass transfer processes were investigated in papers [7,8] but their results cannot be used directly for the problems connected with the processes in nanoporous medium.…”
