Abstract

The states of an electron confined in a two-dimensional (2D) plane and bound to an off-plane donor impurity center, in the presence of a magnetic field, are investigated. The energy levels of the ground state and the first three excited states are calculated variationally. The binding energy and the mean orbital radius of these states are obtained as a function of the donor center position and the magnetic field strength. The limiting cases are discussed for an in-plane donor impurity (i.e. a 2D hydrogen atom) as well as for the donor center far away from the 2D plane in strong magnetic fields, which corresponds to a 2D harmonic oscillator.

Main findings

Electron states confined to a 2D plane and bound to an off-plane donor impurity in the presence of a magnetic field were investigated. Energy levels for the ground state and first three excited states were calculated variationally, and binding energy and mean orbital radius were obtained as functions of donor position and magnetic field strength; limiting cases corresponding to a 2D hydrogen atom and a 2D harmonic oscillator were discussed.
