Adsorption Induced Semiconductor to Metal Transition in Tellurium Nanowires
Semiconductor to metal (S-M) transition usually requires application of high pressure, or chemical/compositional transformation of materials. In this paper, in contrast to the usual severe conditions, we show that ultrathin trigonal Te nanowires undergo S-M transition upon simple adsorption of NO2. This phenomenon was predicted by DFT calculations, and was verified by R-T measurements (courtesy: Prof. Aveek Bid's lab, Physics, IISc) on the Te nanowires synthesized wet-chemically in our lab. This is one of the many examples of our collaborative works. To know more, see our paper in ACS Appl. Mater. & Interfaces
