Phase diagrams of Bi 1−x Sb x thin films with different growth orientations

Year: 2012

Type: article

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${}_{1\ensuremath{-}x}$Sb${}_{x}$ thin films that are grown along different crystalline axes. The phase diagrams for the Bi${}_{1\ensuremath{-}x}$Sb${}_{x}$ thin film systems with different growth orientations are calculated and analyzed.
