Non-collinear and strongly asymmetric polar moments at back-gated SrTiO3 interfaces
Fryderyk Lyzwa, Yurii G. Pashkevich, Premysl Marsik +15
The highly mobile electrons at the interface of SrTiO3 with other oxide insulators, such as LaAlO3 or AlOx, are of great current interest. A vertical gate voltage allows controllin…
Anomalous Anisotropic Exciton Temperature Dependence in Rutile TiO2
Edoardo Baldini, Adriel Dominguez, Letizia Chiodo +5
Elucidating the details of the electron-phonon coupling in semiconductors and insulators is a topic of pivotal interest, as it governs the transport mechanisms and is responsible f…
Anisotropy of the infrared-active phonon modes in the mono-domain state of tetragonal SrTiO3 (110)
M. Yazdi-Rizi, P. Marsik, B. P. P. Mallett +1
With infrared and terahertz ellipsometry we investigated the anisotropy of the infrared active phonon modes in SrTiO3 (110) single crystals in the tetragonal state below the so-cal…
X-ray absorption study of the ferromagnetic Cu moment at the interface and the variation of its exchange interaction with the Mn moment
K. Sen, E. Perret, A. Alberca +14
With x-ray absorption spectroscopy and polarized neutron reflectometry we studied how the magnetic proximity effect at the interface between the cuprate high- superconductor $…
Strongly bound excitons in anatase TiO2 single crystals and nanoparticles
Edoardo Baldini, Letizia Chiodo, Adriel Dominguez +11
Anatase TiO is among the most studied materials for light-energy conversion applications, but the nature of its fundamental charge excitations is still unknown. Yet it is cruci…
Terahertz ellipsometry study of the soft mode behavior in ultrathin SrTiO3 films
Premysl Marsik, Kaushik Sen, Jarji Khmaladze +3
We present a combined study with conventional far-infrared and time-domain terahertz ellipsometry of the temperature dependent optical response of SrTiO3 thin films (85 and 8.5 nm)…
