Ultralow contact resistance at an epitaxial metal/oxide heterojunction through interstitial site doping Heteroepitaxial growth of Cr metal on Nb-doped SrTiO3(001) is accompanied by Cr diffusion to interstitial sites within the first few atomic planes, an anchoring of the Cr film to the substrate, charge transfer from Cr to Ti, and metallization of the near-surface region, The contact resistance of the resulting interface is exceedingly low.

The impacts of cation stoichiometry and substrate surface quality on nucleation, structure, defect formation, and intermixing in complex oxide heteroepitaxy-LaCrO3 on SrTiO3(001). The ability to fabricate electronic devices based on complex oxides critically depends on the ability to controllably synthesize thin films of these materials. We report the effect of cation stoichiometry on structural quality and defect formation in LaCrO3 heteroepitaxial films and show that cation mixing occurs at the interface for all La-to-Cr ratios investigated.

Bio. I obtained my BSc (1994) and MSc (1996) degrees from St. Petersburg State University and PhD in Physics (2000) from the University of London. Following this, I worked as a post-doctoral researcher at University College London and was appointed an Associate Professor at Tohoku University in Japan in 2008.
