The growth of semiconductor nanostructures and the study of their properties have been very active areas of research nano-device application. These novel nanostructures offer interesting prospects for the development of new electronic and photonic devices. Silicon micro photonics, a technology that merges photonics and silicon microelectronic components, is rapidly evolving. The main challenge is to develop efficient light sources out of silicon or silicon based materials. This allows one to combine the information-processing and information transport capabilities of electrons and photons on...
