Quantum size effect in nanosize semiconductor materials

Nanotechnology has given us the ground to play with the ultimate toy box of nature i. e. atoms and molecules. Everything is made from it and hence the possibilities to create new things appear limitless that holds great potential for improving our lives. The nanoscale materials have high surface to volume ratio, which dramatically changes its electrical, optical and magnetic properties as that of bulk material due to Quantum size effect. Recently this concept was playing important role in the development of electronic industry especially nano-devices.
