A spectroscopic study of Na+-bound electrons at Si-SiO2 interfaces

  • 1. Technische Univ. Muenchen, Garching (Germany, F.R.). Fakultaet Physik

Description

For interfaces contaminated with Na+ ions in the concentration range approx. equal to 1011 cm-2 we observe an absorption peak for infrared radiation polarized parallel to the surface. The peak is observed in a gate-voltage sweep at low electron densities. Its amplitude grows linearly with concentration of Na+ and is found for a broad range of frequencies in the 10 meV range.
