Resonant Second-Harmonic Phase Spectroscopy of the Buried Interfaces of Column IV Semiconductors
Abstract
The second-harmonic interferometric spectroscopy (SHIS) is proposed as a new spectroscopic technique to study the resonant electron response of solid state nanostructures. The combination of the second-harmonic (SH) amplitude and phase spectra is shown to be more sensitive to resonant parameters of the electron density of states in comparison with the conventional SH intensity measurements. The resonant anisotropic SH response of buried oxidized Si(111) and Ge(111) surfaces is studied using SHIS in the vicinity of the E(2) critical points. Both spectra of the phase and amplitude of the SH field with different lineshapes for Si and Ge surfaces are obtained.
