 | Liu, Feng | Hydrogen induced Si surface segregation on Ge-covered Si(001) | Using Fourier transform infrared-attenuated total reflectance spectroscopy in conjunction with hydrogen adsorption to probe surface layer composition, we observe a reversible place exchange between Ge and Si on Ge-covered Si(001) when the surface is dosed with atomic H at elevated temperatures.

 | Liu, Feng | Interplay of stress, structure, and stoichiometry in Ge-covered Si(001) | By calculating the evolution of surface energies and surface stress tensors of Ge-covered Si(001) with increasing Ge coverage, we derive the most probable Ge stoichiometry in the subsurface regions beyond 1 monolayer coverage. We compare the calculated surface reconstruction and surface stress at th... | Ge-covered; Si(001); Stress; Structure; Surface stress tensors | 1996-04 |
