Atomic-scale visualization of initial growth of homoepitaxial SrTiO3 thin film on an atomically ordered substrate
Ryota Shimizu, Katsuya Iwaya, Takeo Ohsawa +4
The initial homoepitaxial growth of SrTiO3 on a (\surd13\times\surd13) - R33.7°SrTiO3(001) substrate surface, which can be prepared under oxide growth conditions, is atomically res…
Thickness-dependent Local Surface Electronic Structures of Homoepitaxial SrTiO3 Thin Films
Takeo Ohsawa, Katsuya Iwaya, Ryota Shimizu +2
We have investigated the atomically-resolved substrate and homoepitaxial thin film surfaces of SrTiO3(001) using low-temperature scanning tunneling microscopy/spectroscopy (STM/STS…
Atomically Resolved Surface Structure of SrTiO3(001) Thin Films Grown in Step-Flow Mode by Pulsed Laser Deposition
Katsuya Iwaya, Takeo Ohsawa, Ryota Shimizu +2
The surface structure of SrTiO3(001) thin films homoepitaxially grown by PLD in step-flow mode was characterized using low temperature STM. It was found that one-dimensional (1D) T…
