Self-healing in unpassivated and passivated CdTe nanostructures: structural stability and optical properties

Abstract

We report the effects of passivation on the various properties like electronic structure, structural stability and optical properties of CdTe in the different nanostructure forms such as ultra-thin slabs, monolayers, nanorods and nanotubes. Further, based on these properties, the self-healing ability of each nanostructure has been predicted. The optical properties suggest that all of the passivated and specific unpassivated nanostructures are suitable for optoelectronic applications. The 2D system in <110> orientation and nanotube derived from the <111> monolayer show significant self-healing in the pristine structures.
