ABSTRACT
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.

    We report on the growth and characterization of CdTe quantum dots on Si(111) by direct island nucleation. The samples were grown by hot wall epitaxy on Si(111) substrates treated with diluted HF solution only and the resulting hydrogen-terminated surface permitted the growth of good quality CdTe...
