Abstract

HgTe nanotubes have been prepared by spray deposition of solvothermally synthesized iodine doped HgTe nanoparticles on glass substrates at low temperature (200°C). Spray deposition was done without voltage and with an externally applied voltage (700 V) to the nozzle and it is found from TEM studies that the length of the nanotubes increases from ∼4µm in case of without voltage to ∼ 6µm in case of the applied voltage, with an average diameter of ∼ 45nm. The nanotubes are found to have cubic lattice structure having Hg:Te in stoichimetric ratio (52:48).
