Silicon: electrochemistry and luminescence

Abstract

The electrochemistry of crystalline and porous silicon and the luminescence from porous silicon has been studied. One chapter deals with a model for the anodic dissolution of silicon in HF solution. In following chapters both the electrochemistry and various ways of generating visible luminescence from porous silicon is investigated. Both under cathodic and anodic polarization emission can be observed in the presence of oxidizing and reducing agents, respectively. Also in indifferent electrolyte solutions visible light is found due to oxidation of the porous semiconductor.
