Photoelectron spectroscopic studies on a silicon interface with Bi2Sr2CaCu2BO8+δ high T c superconductor

Abstract
X‐ray and ultraviolet photoelectron spectroscopies have been used to investigate the interaction between silicon and Bi2Sr2CaCu2O8+δ high Tc superconducting material. For low coverages, silicon adatoms disrupt CuO bonds and SrO bonds to form a complex Sr‐Si‐O phase. This interlayer efficiently prevents further reaction between silicon and the Bi2Sr2CaCu2O8+δ superconductor.
