Abstract:
The growth of gallium nitride nanowires on c-plane sapphire substrates using binary catalytic alloy was investigated by manipulating growth time and precursor-to-substrate distance. The variations in structural, optical and morphological behaviour of the samples at different growth conditions were observed using X-ray diffractometer, cathodoluminescence spectroscopy and scanning electron microscopy. It was noticed that, thickness of the nanowires decreased with increase in growth time and precursor-tosubstrate distance. Simultaneously, length of the nanowires increased with growth time and varied with precursor-to-substrate distance. The reduction in nanowire thickness was found to have a positive effect in improving luminescence property and bandgap of the grown nanowires. The results indicate that this material system can be catered for optoelectronic device applications.

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.
