Energy band-gap engineering of graphene nanoribbons.
We investigate electronic transport in lithographically patterned graphene ribbon structures where the lateral confinement of charge carriers creates an energy gap near the charge neutrality point. Individual graphene layers are contacted with metal electrodes and patterned into ribbons of varying widths and different crystallographic orientations. The temperature dependent conductance measurem...
متن کاملBand Gap Engineering of Two-Dimensional Nitrogene
In our previous study, we have predicted the novel two-dimensional honeycomb monolayers of pnictogen. In particular, the structure and properties of the honeycomb monolayer of nitrogen, which we call nitrogene, are very unusual. In this paper, we make an in-depth investigation of its electronic structure. We find that the band structure of nitrogene can be engineered in several ways: controllin...
متن کاملBand gap engineering of MoS2 upon compression
We study the electronic structure of MoS2 upon both compressive and tensile strains with firstprinciples density-functional calculations. We consider monolayer, bilayer, few-layer and bulk MoS2 in the ±15 % strain range, relevant for recent experiments. We assess the stability of the compression calcualting the critical strain that results in the on-set of buckling for nanoribbons of different ...
متن کاملBand Gap of Hexagonal InN and InGaN Alloys
A survey of most recent studies of optical absorption, photoluminescence, photoluminescence excitation, and photomodulated reflectance spectra of single-crystalline hexagonal InN layers is presented. The samples studied were undoped n-type InN with electron concentrations between 6 1018 and 4 1019 cm– 3. It has been found that hexagonal InN is a narrow-gap semiconductor with a band gap of about...
متن کاملDirect Band Gap Gallium Antimony Phosphide (GaSbxP(1-x)) Alloys.
Here, we report direct band gap transition for Gallium Phosphide (GaP) when alloyed with just 1-2 at% antimony (Sb) utilizing both density functional theory based computations and experiments. First principles density functional theory calculations of GaSbxP(1-x) alloys in a 216 atom supercell configuration indicate that an indirect to direct band gap transition occurs at x = 0.0092 or higher S...
