Electrical Characterization of Tailored MoS₂ Nanostructures

Abstract

We try to understand the photocurrent generated in the tailored Molybdenum disulphide (MoS2) nanostructures which were exfoliated from bulk MoS2 powder by a simple liquid phase exfoliation followed by microwave treatment. Sonication and microwave treatment led to the formation of mostly hollow tailored MoS2 nano-rods and nano-spheres which consist of more metallic 1T phase than semiconducting 2H phase. In this paper the interaction of light with these nanostructures and the generation of photocurrent is of peer interest. Confinement of photon in the hollow nanostructures could be very promising to derive photocurrent which can have applications in various optoelectronic devices.
