Reduction of charge fluctuation energies in ultrathin NiO films on Ag(001)
Seolun Yang, H. -K. Park, J. -S. Kim +6
We investigate on-site Coulomb interaction energy between two 3p holes U(Ni 3p) of ultrathin NiO films on Ag(001) by both x-ray photoelectron spectroscopy and Auger electron spectr…

Surface versus bulk characterization of the electronic inhomogeneity in a VO_{2} film
Y. J. Chang, J. S. Yang, Y. S. Kim +6
We investigated the inhomogeneous electronic properties at the surface and interior of VO_{2} thin films that exhibit a strong first-order metal-insulator transition (MIT). Using t…

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,…
