Monohydride Formation on Vicinal Si(001) Investigated by Reflectance Anisotropy Spectroscopy [PDF]

physica status solidi (a), 1999
We report reflectance anisotropy spectroscopy (RAS) results for the controlled dosing of atomic hydrogen onto a clean 3 offcut Si(001)±(1 2) sample, cut so as to expose a single domain under ultra-high vacuum (UHV) conditions. Upon dosing approximately 0.8 monolayers of atomic hydrogen onto this surface at room temperature, followed by annealing, large
