Raman scattering from porous silicon layer into which silver is immersion-p
lated was studied. Ag-deposited samples show extra Raman bands. Heat treatm
ent of the Ag-deposited samples results in a great decrease in such Raman b
ands. Also dipping in hydrofluoric acid solution causes a spectral change.
Some comments on the assignment of the Raman peaks of the Ag-deposited poro
us silicon are given, and the structure of porous silicon on which metal is
immersion-plated is discussed.
