Polaron binding energy and effective mass are calculated for semiconductors with wurtzite crystalline structure from the first order electron-phonon corrections to the self-energy. A recently introduced Fröhlich-like electron-phonon interaction Hamiltonian which accounts for the LO and TO polarizations mixing due to the anisotropy is used in the calculation. The polaronic damping rates are eval...

Highly soluble, non-aggregated colloidal wurtzite InN nanocrystals were obtained through an ambient pressure, low-temperature method followed by post-synthesis treatment with nitric acid.

   A simple low-cost solvothermal method was applied to synthesize hexagonal wurtzite Cu2ZnSnS4 (CZTS) nanoparticles with different morphologies using Polyvinylpyrrolidone (PVP) as a capping ligand and copper and zinc acetate salts at 180 and 220 ℃. The resulting sphere-like and flower-like nanoparticles synthesized at 180 and 220℃</...

We present two models for the atomic structure of inversion domain boundaries in wurzite GaN, that have not been discussed existing literature. Using density functional theory, we find one these has a lower formation energy than previously proposed model known as Holt-IDB. Although this newly higher accepted lower-energy structure, IDB*, argue it can be formed under typical growth conditions. e...

Suitable tight-binding models for wurtzite III–V (non-nitride) and group-V materials are presently missing in the literature. Many commonly used nearest neighbor cubic-zincblende semiconductors result highly inaccurate band structures when transferred to hexagonal polytypes. Wurtzite parameters would be of use modeling nanowires that primarily condense into either or zincblende crystal phases. ...

The electronic and optical properties of CdSe in two phases, cubic and wurtzite, have been studied by first principal calculations using the density functional theory. The optical parameters such as transmittance, optical absorption, refractive index and extinction coefficient have been investigated. We have calculated also the band structure, and total/partial density of state using the full p...

This paper reports on the pressure dependence of the optical absorption edge of ZnO in the wurtzite and rock-salt phase, up to 14 GPa. Both vapor-phase monocrystals and pulsed-laser-deposition thin films have been investigated. In both types of samples the wurtzite to rocksalt transition is observed at 9.7G0.2 GPa. The absorption tail of the fundamental gap, as measured in monocrystals, exhibit...
