Abstract(in English) | Photoluminescence (PL) from Si nanocrystals(2.7-5.5nm) embedded in Si0_2 thin films was stud-led. It was found that Si nanocrystals as small as 3-4nm in diameter exhibit a peak in the near infrared region (1.4-1.5eV). As the size decreased, the PL peak shifted to higher energies and its intensity increased. The temperature dependence of the peak energy was found to be very similar to that of the bulk Si crystal. These suggest that the PL peak arises from the recombination of electrons and holes in Si nanocrystals. At low temperature (<150K), another peak probably associated with the defects at Si-SiO_2 interface was observed at about 0.9eV. |
