Towards efficient band structure and effective mass calculations for III-V direct band-gap semiconductors

The band structures and effective masses of III-V semiconductors InP, InAs, InSb, GaAs, and GaSb are calculated using the GW method, the Heyd, Scuseria, and Ernzerhof hybrid functional, and modified BeckeJohnson combined with the local-density approximation MBJLDA —a local potential optimized for the description of the fundamental band gaps F. Tran and P. Blaha, Phys. Rev. Lett. 102, 226401 200...

Band-Gap Tuning Of Electron Beam Evaporated Cds Thin Films

The effect of evaporation rate on structural, morphological and optical properties of electron beam evaporated CdS thin films have been investigated. CdS thin film deposited by electron beam evaporation method in 12nm/min and 60nm/min evaporation rates on glass substrates. X-ray diffraction, scanning electron microscopy, UV-Vis-NIR spectroscopy and Atomic Force Microscopy were used to character...

Lithographic band gap tuning in photonic band gap crystals

We describe the lithographic control over the spectral response of three-dimensional photonic crystals. By precise microfabrication of the geometry using a reproducible and reliable procedure consisting of electron beam lithography followed by dry etching, we have shifted the conduction band of crystals within the near-infrared. Such microfabrication has enabled us to reproducibly define photon...

Nature of the band gap of In2O3 revealed by first-principles calculations and x-ray spectroscopy.

Bulk and surface sensitive x-ray spectroscopic techniques are applied in tandem to show that the valence band edge for In2O3 is found significantly closer to the bottom of the conduction band than expected on the basis of the widely quoted bulk band gap of 3.75 eV. First-principles theory shows that the upper valence bands of In2O3 exhibit a small dispersion and the conduction band minimum is p...
