Study of electron-phonon couplings at interfaces by doubly resonant sum frequency generation spectroscopy

Project: Research

Description

The non linear mixing of tunable infrared and visible laser beams is observed at selected interfaces as a function of both infrared and visible frequencies. Vibrational resonances are revealed by scanning the infrared range. Electronic enhancement of these resonances is then observed by varying the visible frequencies.
