## Abstract We report photoluminescence (PL) and Raman scattering (RS) measurements of (111) oriented Ge nanowires (NWs) grown by chemical vapor deposition on (100) and (111) silicon substrates. Our PL measurements strongly suggest that the observed emission originates at lowβdefect density Ge NW β

Abstract
The cover picture of the present issue of physica status solidi (a) contains two scanning electron micrographs showing approximately 40 nm diameter Ge nanowires grown by the vaporβliquidβsolid (VLS) technique on Si(100) (upper right figure) and Si(111) (lower left figure) substrates, respectively. The figures are provided by the authors T. I. Kamins (HewlettβPackard Laboratories) and L. Tsybeskov (New Jersey Institute of Technology).

## Abstract A comprehensive characterization of the optical properties of wurtzite InN films grown by molecular beam epitaxy on Si(111) substrates is presented. Two types of films are investigated in this work: InN on AlN/Si(111) and InN on GaN/AlN/Si(111). Their properties are compared to a layer
The photoluminescence (PL) of undoped, Si-doped, and Be-doped GaAs nanowires (NWs) grown on Si substrates by molecular beam epitaxy was investigated. PL peaks of the undoped and Be-doped NWs were observed at higher energies than the bandgap energy of GaAs bulk. According to X-ray diffraction analysi
