A comparison of resonant tunneling based on Schrödinger's equation and quantum hydrodynamics

Abstract

Smooth quantum hydrodynamic (QHD) model simulations of the current-voltage of a resonant tunneling diode at 300 K are compared with that predicted by the mixed-state Schrödinger equation approach. Although the resonant peak for the QHD simulation occurs at 0.15 V instead of the Schrödinger equation value of 0.2 V, there is good qualitative agreement between the current-voltage curves for the two models, including the predicted peak current values.
