Optical second-harmonic electro- and thermoreflectance spectroscopy of silicon(001)/silicon dioxide, hydrogen-silicon(001), and silicon(001)-(2 x 1) interfaces by femtosecond pulses

e report a comprehensive study of the dependence of the second harmonic (SH) spectrum of a Si(001) metal-oxide-semiconductor (MOS) structure on applied bias, and of the SH spectrum of a clean Si(001) surface on hydrogen termination and temperature, in the vicinity of the direct two-photon...
