Energy Level Width of 2DEG in Different Well in Mesoscopic System

Abstract:

Applying theories on quasi-classical particles and the uncertainty relation of quantum mechanics, we get the formula of uncertainty and energy level width in triangular well and parabolic well of two dimension electron gas (2DEG).Based on these ,we find energy width will increase along with the increasing of electronic field intensity and quantum number at the same electronic field, the energy width of parabolic well is more narrow than width of triangular well. At the same time, the result of this paper is agreement with the experiment.
