Porous silicon (PS) samples fabricated using different electrochemical
conditions are studied. A correlation between film porosity and the e
nergy E, provided to the silicon/HF system, is found. The dependence o
f the etched mass on E is also investigated. A maximum for the porosit
y is found to exist. The conditions for fabricating PS samples emittin
g in the visible region are given.
