Impurity-bound electron in quantum well-heterostructure-type systems

Özdinçer, Uğur

The ground-state binding energy of a hydrogenic impurity is retrieved as a function of the effective dimensionality in a quantum well confinement. The geometry we use is a rectangular box, the dimensions of which can be tuned so as to yield a unified description interpolating between the bulk, the quasi-two- and one-dimensional limits as well as the quantum well box case.
