Temperature-Dependent Electron-Electron Interaction in Graphene on SrTiO3
Hyejin Ryu, Jinwoong Hwang, Debin Wang +6
The electron band structure of graphene on SrTiO3 substrate has been investigated as a function of temperature. The high-resolution angle-resolved photoemission study reveals that…
Hole doping, hybridization gap, and electronic correlation in graphene on a platinum substrate
Jinwoong Hwang, Hwihyeon Hwang, Min-Jeong Kim +7
The interaction between graphene and substrates provides a viable routes to enhance functionality of both materials. Depending on the nature of electronic interaction at the interf…
Multiband behavior and non-metallic low-temperature state of KNaFeSe
Hyejin Ryu, F. Wolff-Fabris, J. B. Warren +3
We report evidence for multiband transport and an insulating low-temperature normal state in superconducting KNaFeSe with K. The…
Spin glass in semiconducting KFeAgTe single crystals
Hyejin Ryu, Hechang Lei, B. Klobes +3
We report discovery of KFeAgTe single crystals with semiconducting spin glass ground state. Composition and structure analysis suggest nearly stoichiometric…
Insulating and metallic spin glass in KFeNiSe (0.06 1.44) single crystals
Hyejin Ryu, Milinda Abeykoon, Kefeng Wang +6
We report electron doping effects by Ni in KFeNiSe (0.06 1.44) single crystal alloys. A rich ground state phase diagram is observed. S…
Sustained phase separation and spin glass in Co-doped KFeSe single crystals
Hyejin Ryu, Kefeng Wang, M. Opacic +5
We present Co substitution effects in KFeCoSe (0.06 1.73) single crystal alloys. By 3.5\% of Co doping superconductivity is suppressed…
