Optical Signature of a Crossover from Mott- to Slater-type Gap in SrIrRhO
B. Xu, P. Marsik, E. Sheveleva +5
With optical spectroscopy we provide evidence that the insulator-metal transition in SrIrRhO occurs close to a crossover from the Mott- to the Slater-type.…
Infrared ellipsometry study of the photo-generated charge carriers at the (001) and (110) surfaces of SrTiO crystals and the interface of corresponding LaAlO/SrTiO heterostructures
M. Yazdi-Rizi, P. Marsik, B. P. P. Mallett +7
With infrared (IR) ellipsometry and DC resistance measurements we investigated the photo-doping at the (001) and (110) surfaces of SrTiO (STO) single crystals and at the corres…
Infrared ellipsometry study of the confined electrons in a high-mobility -AlO/SrTiO heterostructure
Meghdad Yazdi-Rizi, Premysl Marsik, Benjamin Mallett +5
With infrared ellipsometry we studied the response of the confined electrons in a -AlO/SrTiO heterostructures in which they originate predominantly from oxygen vacan…
Optical probe of ferroelectric order in bulk and thin film perovskite titanates
M. Rössle, C. N. Wang, P. Marsik +8
We have measured the temperature dependence of the direct band gap, , in SrTiO and BaTiO and related materials with quantum-paraelectric and ferroelectric prope…
Optical identification of hybrid magnetic and electric excitations in Dy3Fe5O12 garnet
P. D. Rogers, Y. J. Choi, E. Standard +10
Far-infrared spectra of magneto-dielectric Dy3Fe5O12 garnet were studied between 13 and 100 cm-1 and at low temperatures between 5 and 80 K. A combination of transmission, reflecti…
Electron spin relaxation in organic semiconductors probed through muSR
Laura Nuccio, Leander Schulz, Maureen Willis +5
Muon spin spectroscopy and in particular the avoided level crossing technique is introduced, with the aim of showing it as a very sensitive local probe for electron spin relaxation…
