When dimensions of material approach nanoscale, they often reveal startling properties. These unique properties when compared to bulk material make them interesting candidates for new technologies. In a race to sustain Moore's Law, silicon nanowires which possess remarkable properties diverse from bulk-silicon have gained notable attention. With advancement in technology engineers have mastered the art of fabrication of nanowires, but there exists a big gap in understanding various phenomena at this scale. The aim of this work is to bridge the gap and give an insight into some interesting...
