Abstract

Quantum wire and dot nanostructures have been the subject of much theoretical and experimental investigation in recent years owing to the promise these structures hold for improved or novel optoelectronic device applications.^1,2 Theoretical models of the band structure of these systems so far have required physically unrealistic assumptions such as the neglect of band coupling^1,2 and/or the use of infinite band discontinuities to render the Schrodinger equation separable for square potentials.³ Alternately, approximation methods have been applied such as the variational technique.⁴
