摘要:
X‐ray and ultraviolet photoelectron spectroscopies have been used to investigate the interaction between silicon and Bi2Sr2CaCu2O8+&dgr;highTcsuperconducting 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+&dgr;superconductor.
