Anharmonic oscillator model of a quantum dot nanostructure
- 1. Ames Laboratory and Department of Physics, Iowa State University, Ames, Iowa 50011
Description
The energy level spacings observed recently in resonant tunneling through an axially symmetric double-barrier quantum dot structure are reproduced by an isotropic two-dimensional anharmonic oscillator model. We propose that the extent of the depletion region in such a device effectively controls the possible angular momentum states of those electrons contributing to the current-voltage curve
