Nh. Zoubir et al., INTERPRETATION OF THE LUMINESCENCE QUENCHING IN CHEMICALLY ETCHED POROUS SILICON BY THE DESORPTION OF SIH3 SPECIES, Applied physics letters, 65(1), 1994, pp. 82-84
The effect of thermal annealing on chemically etched porous silicon wa
s studied by combined photoluminescence, infrared spectrometry, and th
ermal-desorption spectrometry experiments. The results show that the r
elease of SiH3 and SiF3 entities is a first step in the photoluminesce
nce degradation in porous silicon. These entities desorb before molecu
lar hydrogen.
