Nowadays Monte Carlo (MC) method becomes a very important tool to simulate the diffusion length by electron-matter interaction. In this research, we propose a new Monte Carlo calculation of electron depth and energy dissipation in silicon. Keywords: EBIC;minority carrier;diffusion length;calculation;Si
