摘要:
The In/BRBO/STO specimens were fabricated by depositing Ba0.6Rb0.4Bi1.0Oy (BRBO) on the SrTiO3 (STO) substrates by means of molecular beam epitaxy using 100% pure ozone and then, by depositing In metal. From the X-ray photoelectron spectroscopy results, we found that the In metal deposited on the BRBO/STO specimen removed the oxygen from BRBO and produced InOx layer at the interface between In metal and BRBO.
