An efficient self-consistent model for resonant tunneling structures

Abstract
We present an efficient self-consistent current-voltage model for the double-barrier resonant tunneling (RT) structure. In the existing self-consistent models, normalized wave functions are used to describe the distribution of space charge in the RT structure. The present model, instead, uses the concept of group velocities for electrons. The use of group velocities for electrons simplifies the model by eliminating the need for the calculation of normalized wave functions.
