Ly. Hao et al., EMISSION-SPECTRUM OF SILICON IN THE REGION OF ANOMALOUS DISPERSION, Physical review. B, Condensed matter, 47(20), 1993, pp. 13320-13322
We report measurements of emission spectra of single-crystal silicon b
y electron impact in the region of anomalous dispersion at room temper
ature. The spectral range extends from 2500 to 6500 angstrom. Direct o
ptical transitions in the band structure of Si correspond to the spect
rum feature obtained; the spectrum peaks occur in the region where the
extinction coefficient k decreases rapidly.
