Paper Abstract

One dimensional superstructures are of great interest in the field of optics, opto-electronics and photonics. Over a period of time, researchers have developed various new and low cost techniques to prepare nanostructures of metals as well as semiconductors. We found that ionic liquid can be used to synthesis nanostructured film directly on the substrate by means of electrodeposition. It was found that spindle like CdTe superstructure assemblies over the commercial F:SnO2 substrate gives a Schottky junction, resulting in the highest rectification ratio of 6000. It was also possible to manipulate the dimensions of structures by changing the precursor molar ratio in the ionic liquid bath. It was observed that by varying the structure size, electrical properties of the diodes improve significantly. The admittance measurements reveal that by increasing the length and diameter of the structures, the conductance of the diode increases linearly. We believe that proper arrangement of the fabricated CdTe thin films will find many applications in near future.
