Bismuth thin film
WebNov 14, 2024 · Bismuth oxide thin films in particular are studied often because they have unique properties such as a high refractive index, semiconductivity, and a large energy … 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.
