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,…
Ferroelectric properties of SrRuO3/BaTiO3/SrRuO3 ultrathin film capacitors free from passive lay
Y. S. Kim, J. Y. Jo, D. J. Kim +9
Structural studies on ultrathin SrRuO3/BaTiO3/SrRuO3 capacitors, with BaTiO3 thicknesses of between 5 nm and 30 nm, show well-defined interfaces between ferroelectric BaTiO3 and el…
Optical investigations on : Electronic structure evolutions related to the metal-insulator transition
J. S. Lee, S. J. Moon, T. W. Noh +4
Optical conductivity spectra of cubic pyrochlore (0.0{\it x}2.0) compounds are investigated. As a metal-insulator transition (MIT) occurs arou…
The effect of lattice distortion and orbital mixing on the optical and magnetic properties of cubic RMnO (R = La, Pr, Nd, Gd, Tb)
M. W. Kim, S. J. Moon, J. H. Jung +4
We investigated the -plane absorption spectra of MnO ( = La, Pr, Nd, Gd, and Tb) thin films. As the -ion size decreases, we observed a drastic suppression of th…
Orbital-selective Mass Enhancements in Multi-band CaSrRuO Systems Analyzed by the Extended Drude Model
J. S. Lee, S. J. Moon, T. W. Noh +2
We investigated optical spectra of quasi-two-dimensional multi-band CaSrRuO systems. The extended Drude model analysis on the ab-plane optical conductivity s…
