Optical properties of [001] GaN nanowires- An ab-initio study

Agrawal B.K., Agrawal S., Pathak A., Agrawal B.K., Agrawal S., Allahabad University, IN

We study the physical properties of the unpassivated and H-passivated GaN nanowires (NWs) by employing the first–principles pseudopotential method within density functional theory (DFT). Two types of the NW’s having hexagonal and triangular cross-sections have [...]

Carbon nanotube superlattices- An oscillatory metallic behaviour

Agrawal B.K., Pathak A., Allahabad University, IN

The physical properties of the (n,n)/(2n,0); n = 3 and 6 superlattices of the carbon nanotubes (CN’s) has been studied by employing the first–principle pseudopotential method. The curvature effects on the various properties are also [...]
