Semiconductor nanowire optoelectronic devices

Semiconductor nanowires act as waveguides despite very small cross-section dimensions because of high refractive indices. The waveguiding properties of nanowires alter the way the semiconductor material interacts with light. We elaborate on the waveguiding properties of nanowires and the effect of these properties on the spontaneous emission characteristics of nanowires. The effect of waveguiding properties of nanowires on optoelectronic devices like nanowire solar cells and lasers is also discussed
