Hybridization gap and -electron effect evolutions with Cd- and Sn-doping in CeCoIn via infrared spectroscopy

Myounghoon Lee, Yu-Seong Seo, Seulki Roh +4

We investigated hole (Cd)- and electron (Sn)-doped CeCoIn (CeCo(In) ( = Cd or Sn)) using infrared spectroscopy. Doping-dependent hybridization gap distributio…

Temperature-dependent -electron evolution in CeCoIn via a comparative infrared study with LaCoIn

Myounghoon Lee, Yu-Seong Seo, Seulki Roh +6

We investigated CeCoIn and LaCoIn single crystals, which have the same HoCoGa-type tetragonal crystal structure, using infrared spectroscopy. However, while CeCoIn…

Electron-hole symmetry in quasiparticle spectral weight of cuprates observed via infrared and photoemission spectroscopy

Myounghoon Lee, Dongjoon Song, Yu-Seong Seo +4

We performed an optical spectroscopy study on single crystals of PrLaCeCuO (PLCCO) to revisit the electron-hole asymmetry, which has been understood as a…

Evolution of electronic structure of Ru-doped single-crystal iridiates, SrIrRuO

Seokbae Lee, Yu-Seong Seo, Eilho Jung +7

We investigated Ru-doped single-crystal 5 iridiates, SrIrRuO, at three different doping concentrations ( 0.01, 0.07 and 0.10) using optical spectrosco…

Color of Copper/Copper oxide

Su Jae Kim, Seonghoon Kim, Jegon Lee +16

Stochastic inhomogeneous oxidation is an inherent characteristic of copper (Cu), often hindering color tuning and bandgap engineering of oxides. Coherent control of the interface b…

Magnetic-order-driven metal-insulator transitions in the quasi-one-dimensional spin-ladder compounds BaFeS and BaFeSe

Seulki Roh, Soohyeon Shin, Jaekyung Jang +9

The quasi-one-dimensional spin ladder compounds, BaFeS and BaFeSe, are investigated by infrared spectroscopy and density functional theory (DFT) calculations. We ob…

Oxygen vacancy-induced structural evolution of SrFeO epitaxial thin film from brownmillerite to perovskite

Seulki Roh, Seokbae Lee, Myounghoon Lee +8

We investigated SrFeO thin films on a SrTiO (001) substrate prepared via pulsed laser epitaxy using an optical spectroscopy technique. The oxygen vacancy level () wa…
