Abstract
A closed-form model is developed to evaluate the band-edge shift caused by quantum confinement for a two-dimensional nonparabolic carrier pocket. Based on this model, the symmetries and the band shifts of different carrier pockets are evaluated for Bi[subscript 1−x]Sb[subscript x] thin films that are grown along different crystalline axes. The phase diagrams for the Bi[subscript 1−x]Sb[subscript x] thin film systems with different growth orientations are calculated and analyzed.
