Plasmonic polaron in self-intercalated 1T-TiS2
Byoung Ki Choi, Woojin Choi, Zhiyu Tao +24
Electron-boson coupling is central to a comprehensive understanding of the diverse physical phenomena emerging from many-body interactions. Yet less attention has been paid to how…
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…
Unusual ferromagnetic band evolution and high Curie temperature in monolayer 1T-CrTe2 on bilayer graphene
Kyoungree Park, Ji-Eun Lee, Dongwook Kim +17
2D van der Waals ferromagnets hold immense promise for spintronic applications due to their controllability and versatility. Despite their significance, the realization and in-dept…
Quasidegenerate charge-density wave states in 1T-TiSe
Seungrok Mun, Woojin Choi, Hayoon Im +4
Transition metal dichalcogenides have been actively studied for their intriguing charge density wave (CDW) formations and their impacts on material properties. Among these, 1T-TiSe…
Spin-orbit-splitting-driven nonlinear Hall effect in NbIrTe4
Ji-Eun Lee, Aifeng Wang, Shuzhang Chen +13
The Berry curvature dipole (BCD) serves as a one of the fundamental contributors to emergence of the nonlinear Hall effect (NLHE). Despite intense interest due to its potential for…
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…
