Meulenkamp, EA and Peter, LM and Riley, DJ and Wielgosz, RI and Penty, RV and Snow, PA and White, IH (1995) Potential tuning of porous silicon luminescence. IEE Colloquium (Digest). 12/1-12/6. ISSN 0963-3308Full text not available from this repository.
Electrochemical investigations were conducted of the effect of potential on the luminescence of porous silico (PS). The use of liquid contacts allows the potential to be controlled during studies of the photoluminescence (PL) and electroluminescence (EI). The PL and EL of PS samples prepared from n-type substrates is considered. To obtain luminescence from such PS it is necessary to generate holes in the valence band. This is achieved by either photoexcitation or an electrochemical process involving the reduction of persulfate. This paper describes the investigations of the effect of potential on the PL and EL of PS. A mechanism of 'potential tuning' based on electron occupancy and Auger quenching is then proposed.
