Porous silicon sheds a new light on OEICs

Research efforts and developments in understanding the origin of the luminescence of porous silicon are reviewed. The fundamental characteristics of porous silicon are outlined. The quantum confinement model, which is used to characterize the luminescence from porous silicon, and porous silicon's optical properties, which show substantial instabilities, are discussed. The research into and applications of electroluminescence using porous silicon are also discussed.<
