Theoretical study of the (110) surface of Sn1Â -Â xTixO2 solid solutions with different distribution and content of Ti

► Stability of the (110) surface of Sn1 - xTixO2 solid solutions was computed by DFT. ► Ti-enrichment on the (110) surface of SnO2 was predicted for all Ti-contents. ► Remarkable corrugations of the (110) surface for low surface Ti-contents. ► Geometry of full TiO2 monolayer on SnO2 determined by underlying SnO2 bulk structure. ► Use of a large (720 atoms) supercell allowed simulation of very low Ti-content.
