\section{Light Emitting Diodes}  LEDs are used in numerous electronics and have many advantages over other light sources. Such as lower energy consumption, longer lifetime, and smaller size. Bae and coworkers have successfully made GaAs NW array based LED on Si.\cite{Bae_2014} The LED could emit light at a peak wave length of $\lambda$ = 830 nm
