Our study investigates the potential of thermal laser epitaxy (TLE) for Si epitaxy. A systematic study on the evaporation behavior of Si during TLE identifies and addresses the causes of notable flux rate fluctuations, resulting in a Si flux with 0.3% stability over time. We also demonstrate heteroepitaxy of Si on -plane sapphire substrates via TLE. High-temperature substrate preparation combined with deposition at a substrate temperature of 1000 C produced high-quality epitaxial Si (111) films without twin domains.
