Liquid phase epitaxy of Si from Pb solutions
Liquid phase epitaxy of Si was performed in a conventional tipping boat system in hydrogen atmosphere. Pure Pb was used as a solvent. Diffusion of Si in Pb solution was the rate determining step of the layer growth. The diffusion coefficient of Si in molten Pb at 987°C was determined to be 3.2×10 −5...
