Giant Hole-doping in 2H-WSe2 via Ta Substitution
Minhee Kang, Woojin Choi, Choongyu Hwang +1
The family of transition metal dichalcogenides (TMDCs) has been regarded as promising candidates for future electronics, valleytronics, spintronics, and optoelectronics. While most…
Band-selective simulation of photoelectron intensity and converging Berry phase in trilayer graphene
Hayoon Im, Sue Hyeon Hwang, Minhee Kang +3
Berry phase is one of the key elements to understand quantum-mechanical phenomena such as the Aharonov-Bohm effect and the unconventional Hall effect in graphene. The Berry phase i…
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…
A plausible method of preparing the ideal p-n junction interface of a thermoelectric material by surface doping
Ji-Eun Lee, Jinwoong Hwang, Minhee Kang +10
Recent advances in two-dimensional (2D) crystals make it possible to realize an ideal interface structure that is required for device applications. Specifically, a p-n junction mad…
Concomitant enhancement of electron-phonon coupling and electron-electron interaction in graphene decorated with ytterbium
Minhee Kang, Jinwoong Hwang, Ji-Eun Lee +2
The interplay between electron-electron interaction and electron-phonon coupling has been one of the key issues in graphene as it can provide information on the origin of enhanced…
Gapped Nearly Free-Standing Graphene on an SiC(0001) Substrate Induced by Manganese Atoms
Jinwoong Hwang, Ji-Eun Lee, Minhee Kang +4
The electron band structure of manganese-adsorbed graphene on an SiC(0001) substrate has been studied using angle-resolved photoemission spectroscopy. Upon introducing manganese at…
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…
