Giant magneto-optical response in non-magnetic semiconductor BiTeI driven by bulk Rashba spin splitting
L. Demkó, G. A. H. Schober, V. Kocsis +7
We study the magneto-optical (MO) response of polar semiconductor BiTeI with giant bulk Rashba spin splitting at various carrier densities. Despite being non-magnetic, the material…
Reduction of high reset currents in unipolar resistance switching Pt/SrTiOx/Pt capacitors using acceptor doping
S. B. Lee, A. Kim, J. S. Lee +7
The high reset current, IR, in unipolar resistance switching is an important issue which should be resolved for practical applications in nonvolatile memories. We showed that,durin…
Optical spectroscopic investigation on the temperature-dependent electronic structure evolution of the Jeff,1/2 Mott insulator Sr2IrO4
S. J. Moon, Hosub Jin, W. S. Choi +6
We investigated the temperature-dependent evolution of the electronic structure of the Jeff,1/2 Mott insulator Sr2IrO4 using optical spectroscopy. The optical conductivity spectra…
Scaling behaviors of RESET voltages and currents in unipolar resistance switching
S. B. Lee, S. C. Chae, S. H. Chang +4
Unipolar switching phenomena have attracted a great deal of recent attention, but the wide distributions of switching voltages still pose major obstacles for scientific advancement…
Strong resistance nonlinearity and third harmonic generation in the unipolar resistance switching of NiO thin films
S. B. Lee, S. C. Chae, S. H. Chang +6
We investigated third harmonic generation in NiO thin films, which exhibit unipolar resistance switching behavior. We found that the low resistance states of the films were strongl…
Optical investigations on electronic structure changes related to the metal-insulator transition in VO2 film
C. H. Koo, J. S. Lee, M. W. Kim +4
We investigated optical absorption coefficient spectra of an epitaxial VO2 film in wide photon energy (0.5 - 5.0 eV) and temperature (100 - 380 K) regions. In its insulating phase,…
