Bismuth stm
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 — α-Bi and β-Bi — were identified from high-resolution X-ray diffraction (XRD) measurements. The crystal structure dependencies on the layer thicknesses of these films were analyzed. β-Bi layers … WebBismuth strontium calcium copper oxide ( BSCCO, pronounced bisko ), is a type of cuprate superconductor having the generalized chemical formula Bi 2 Sr 2 Ca n−1 Cu n O 2n+4+x, with n = 2 being the most commonly studied compound (though n = 1 and n = 3 have also received significant attention).
