摘要
We have applied high-resolution transmission electron energy-loss spectroscopy to explore the electronic structure of a reconstructed defect in the interior of Si crystal. Despite the electronic and optical inactivity of the defects, the L-2,L-3 near-edge structure becomes sharp within the narrow energy range (less than 1 eV) whenever an electron probe locates on the defects. Our analysis based on nb initio computations has suggested that the sharpened near edge arises from the odd-membered atomic ring in the defects. [S0163-1829(98)07140-9].
