Giant polarization anisotropy in optical transitions of free-standing InP nanowires
(2004) In Physical Review B (Condensed Matter and Materials Physics) 70(16).- Abstract
- We report a theoretical study of the electronic structure and optical properties of free-standing semiconductor nanowires, based on an atomistic tight-binding approach. It is shown that the optical transition between the valence-band maximum and conduction-band minimum of an intrinsic nanowire is fully polarized along the wire axis, and this giant polarization anisotropy can be explained in terms of intrinsic band-structure properties of the nanowire. It is also predicted that the optical spectra and polarization ratio of the nanowire can be tuned with temperature and the chemical potential of carriers in the nanowire.
