Abstract:
In this study, Schottky barrier diodes on ‘clump of nanowires’ has been fabricated and its electrical behaviour on variation of distance of separation between Ohmic (Ti/Al/Ni/Au) and Schottky (Ni/Au) contacts has been studied. The variations in current under dark and bright conditions have been investigated. High quality gallium nitride nanowires were grown by chemical vapour deposition technique using gold-palladium alloy as catalyst. The novelty of this work is that, the barrier height remains unaffected irrespective of any variations in the ideality factor. Also, the method of lithography during fabrication did not give rise to any surface related inhomogeneities.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
