Abstract

We study single-particle electronic states of a threedimensional semiconductor quantum ring. Starting from the envelope-function theory, we formulate a fully analytical model for single-particle wave functions and confinement energies of charge carriers. The approximative harmonic-oscillator model is found to be in excellent agreement with numerical results. The model is a powerful tool in practical calculations when there is a need to go beyond single particle properties to more demanding many-body effects.
