Atomic and electronic surface structures of dopants in oxides: STM and XPS of Nb- and La-doped SrTiO3(001)
High resolution X-ray photoelectron spectroscopy (XPS) was performed on the (001) surfaces of Nb-doped and La-doped single crystals of SrTiO3. For the Nb-doped samples the XPS results demonstrate that the fraction of Ti3⊃+ ions increases with increasing Nb dopant concentration. The Nb dopants are sh...
