I am currently looking into the electrical transport properties as well as the optical response of ultra-thin semiconducting Tellurium (Te) nanowires (NWs). The preliminary transport results show that the transport in Te NWs is thermally activated in high temperature (>170K) and in the low temperature (<170K), Mott Variable Range Hopping (VRH) takes place. On the other hand, Te NW serves as an excellent candidate for near-infra red detector, as it is a narrow band-gap semiconductor (~0.6 eV). This allows us to investigate this interesting and highly popular field full of new novel physics of light-matter interaction as well as basic applications.
