LUMINESCENCE FROM DEUTERIUM-TERMINATED POROUS SILICON

Deuterium-terminated silicon nanocrystals were fabricated by electroch emical anodization with DF electrolyte for the first time. Deuterium-t erminated and hydrogen-terminated Si nanocrystals were characterized w ith transmission electron microscope analysis, Raman spectroscopy and Fourier transform infrared spectroscopy, The observed spectrum of phot oluminescence was different despite the same size of the nanocrystals for both Si nanocrystals. These results can be analyzed by the confine d carriers coupling to the surface vibration of terminated atoms on na nocrystals. (C) 1997 Elsevier Science S.A.
