Silicon nanostructures provide intetresting optical and electrical properties making them ideal for a number of applications in optical detection, energy harvesting, bio-chemical sensing etc. In order to optimize the performance of devices consisting of these nanostructures, simulation tools for both the quantum and electromagnetic behavior of these structures are required especially to the experimentalists working in this area. Since, many application use both the properties, simulation tools should consider both the electromagnetic and quantum calculations. No commercial tools exist today in this domain. In this proposal, simulation codes for predicting the optical performance of silicon nanowires and nanostructures is proposed. The codes will include simulating the electromagnetic performance of arrayed and disordered silicon nanowires for applications in solar cells, photodetectors, optical imagers etc. Simulation methodology will include our proposed effective index approximations and Mie-scattering formulation. Codes will also be developed for photon-carrier interactions based on k.p matrix method. Genereated current in the nanowires will be simulated with mode space implementation and non-equilibrum Green's function. The results will be verified with our already published experimental results. At the end of this project, we will deliver all the sub-tools required to simulate optical properties of silicon nanostructures which can be combined into a single simulation tool in future. The success of the project will allow CodeSScientific to take a market lead in providing simulation tools for silicon nanostructures especially for silicon photonics, a field of great interest to Canada.
