Impurity States and diamagnetic susceptibility of a donor in a triangular quantum well
Abstract
We have calculated the binding energy and the diamagnetic susceptibility(χ_{dia}) of the ground (1s) and few low lying excited states (2s and 2p_{±}) in a GaAs/Al_{x}Ga_{1x}As Triangular Quantum Well (TQW) for the Al composition of x = 0.3. Since the estimation of <r^{2}> gives the carrier localization in nanostructured systems and also the calculation of (χ_{dia}) involves the <r^{2}>, the same has also been estimated as a function of well width. The Schrodinger equation has been solved using variational technique involving Airy functions in the effective mass approximation. The results are presented and discussed.
