Titel:
Role of microstructure on optical properties in high-uniformity In 1−x Ga x As nanowire arrays: Evidence of a wider wurtzite band gap 
Abstract:
Accessing fundamental structure-property correlations in ternary semiconductor nanowires is a challenging endeavor often limited by large compositional inhomogeneities. Here, we investigate strongly periodic In 1−x Ga x As nanowire arrays grown on Si with very high compositional uniformity to identify the role of microstructural features (crystal phase and stacking order) on the phonon and optical properties via transmission electron microscopy, Raman, and photoluminescence spectroscopy.
