Abstract

Porous silicon layers fabricated on substrates of different roughness are studied. The photoluminescence characteristics of these samples are reported at room and liquid nitrogen temperature. The initial roughness of the substrates regulates the porous silicon formation mechanism. The results are explained in terms of the quantum confinement model. The rougher the starting substrate, the narrower is the size distribution of the emitting structures. © 1993.
