Second-harmonic generation as a probe of chemically modified Si(111) surfaces and the initial oxidation of hydrogen terminated Si(111)
Optical second-harmonic generation (SHG) is used to probe Si(111) surfaces with covalently attached monolayers. The surfaces are prepared using wet chemical modification to form -H, -C 10 H 21 (decyl) and -O-C 10 H 21 (decyloxy) monolayers. The SHG efficiency for these surfaces as well as a Si(111)...
