Abstract
We have developed an iterative one-dimensional model to study the narrow band gap and the associated nonparabolic dispersion relations for bismuth antimony nanowires. An analytical approximation has also been developed. Based on the general model we have developed, we have calculated and analyzed the electronic phase diagrams and the band-gap/band-overlap map for bismuth antimony nanowires, as a function of stoichiometry, growth orientation, and wire width.
