Topological properties and the dynamical crossover from mixed-valence to Kondo-lattice behavior in golden phase of SmS
Chang-Jong Kang, Hong Chul Choi, Kyoo Kim +1
We have investigated temperature-dependent behaviors of electronic structure and resistivity in a mixed-valent golden phase of SmS, based on the dynamical mean-field theory band st…
Dimerization-Induced Fermi-Surface Reconstruction in IrTe2
Man Jin Eom, Kyoo Kim, Y. J. Jo +6
We report a de Haas-van Alphen (dHvA) oscillation study on IrTe2 single crystals showing complex dimer formations. By comparing the angle dependence of dHvA oscillations with band…
Termination-dependent Surface In-gap States in a Mixed-valent Topological Insulator: SmB
Junwon Kim, Kyoo Kim, Chang-Jong Kang +5
We have investigated the surface states of a potential mixed-valent topological insulator SmB based on the first principles density functional theory slab band structure analys…
Structural instability and the Mott-Peierls transition in a half-metallic hollandite : KCrO
Sooran Kim, Kyoo Kim, B. I. Min
In order to explore the driving mechanism of the concomitant metal-insulator and structural transitions in quasi-one-dimensional hollandite KCrO, electronic stru…
