Tunable Kondo resonance at a pristine two-dimensional Dirac semimetal on a Kondo insulator
Jinwoong Hwang, Seungseok Lee, Ji-Eun Lee +6
Proximity of two different materials leads to an intricate coupling of quasiparticles so that an unprecedented electronic state is often realized at the interface. Here, we demonst…
Emergence of Kondo resonance in graphene intercalated with cerium
Jinwoong Hwang, Kyoo Kim, Hyejin Ryu +11
The interaction between a magnetic impurity, such as cerium (Ce) atom, and surrounding electrons has been one of the core problems in understanding many-body interaction in solid a…
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…
Electronic Griffiths Phase in the Te - Doped Semiconductor FeSb
Rongwei Hu, Kefeng Wang, Hyejin Ryu +5
We report on the emergence of an Electronic Griffiths Phase (EGP) in the doped semiconductor FeSb, predicted for disordered insulators with random localized moments in the vi…
