· Appl. Phys. Lett.; (United States)
Chemical etching of Si(111) surface by chlorine molecules under 355 and 560 nm irradiation has been studied using a continuous wave supersonic molecular beam. Only two products, SiCl and SiCl/sub 2/, were observed. The translational energy distributions of the gaseous products have been measured as a function of laser fluence, and can be fitted with Maxwell--Boltzmann distributions. Study on the effect of translational energy of incident chlorine molecules on the reaction rate is also presented for the first time.
