Bismuth thin film
WebBismuth films with thicknesses between 6 and ∼30 nm were grown on Si (111) substrate by molecular beam epitaxy (MBE). Two main phases of bismuth — -Bi and -Bi — were identified from high-resolution X-ray diffraction (XRD) measurements. The crystal structure dependencies on the layer thicknesses of these films were analyzed. WebMay 21, 1999 · Polycrystalline Bi films of thickness t = 1 to 20 μm deposited at a rate of ∼0.2 μm/min have large grains (0.1 to a few micrometers), but after suitable annealing …
