Abstract :
The rotational-anisotropy second-harmonic generation signal from thermally oxidized Si(001) surfaces shows unusual eightfold symmetry at a critical photon energy. This phase critical-energy varies monotonically with oxide thickness and provides a sensitive probe for interface conditions.
