It is demonstrated that there are distinct off and on states in the current-voltage characteristics of porous silicon ͑PS͒ diodes, and that the visible electroluminescence ͑EL͒ is observed in the on state. The PS diodes are composed of semitransparent thin Au films, rapid thermal oxidization ͑RTO͒-treated PS layers ͑ϳ0.5 m thick͒, p-type Si substrates, and ohmic back contacts. After the PS layers were prepared by anodizing Si wafers in an ethanoic HF solution, the samples were treated by RTOdoi:10.1063/1.122962 fatcat:yd2w2yxv7rax3ch4j5vkspqywi
