Electronic and optical properties of titanate-based oxide superlattices

2015/07/15, Wed, 2PM, E6-1323

Dr. Se Young Park, MIT, Rutgers University, NJ, US

 

 

Progress in pulsed laser deposition and molecular beam epitaxy has provided new ways to control the properties of novel materials, Artificially created oxide systems have been reported to exhibit a range of striking behavior including metal-insulator transitions, superconductivity, and magnetism. But two crucial aspect of these system require further investigation; identifying free and localized carriers and the role of the structural distortion to the metal-insulator transition. In this talk, I will discuss the ellipsometry spectra of the electron gas formed at the interface of LaAlO3 and SrTiO3 to obtain orbital occupancy and high-carrier-density phase in LaTiO3/SrTiO3 superlattices induced by the melting of the Mott-insulating phase  extending from the interface into the LaTiO3 layer.
