The Nature of Bonding in Bulk Tellurium Composed of One-Dimensional Helical Chains
Seho Yi, Zhili Zhu, Xiaolin Cai +2
Bulk tellurium (Te) is composed of one-dimensional (1D) helical chains which have been considered to be coupled by van der Waals (vdW) interactions. However, based on first-princip…
Atomic and electronic structure of doped Si(111)(2root3x2root3)R30(degrees)-Sn interfaces
Seho Yi, Fangfei Ming, Ying-Tzu Huang +8
The hole doped Si(111)(2root3x2root3)R30(degrees)-Sn interface exhibits a symmetry-breaking insulator-insulator transition below 100 K that appears to be triggered by electron tunn…
Competing charge density wave and antiferromagnetism of metallic atom wires in GaN(100) and ZnO(100)
Yoon-Gu Kang, Sun-Woo Kim, Jun-Hyung Cho
Low-dimensional electron systems often show a delicate interplay between electron-phonon and electron-electron interactions, giving rise to interesting quantum phases such as the c…
Microscopic mechanism of tunable band gap in potassium doped few-layer black phosphorus
Sun-Woo Kim, Hyun Jung, Hyun-Jung Kim +3
Tuning band gaps in two-dimensional (2D) materials is of great interest in the fundamental and practical aspects of contemporary material sciences. Recently, black phosphorus (BP)…
Coupling between Charge, Lattice, Orbital, and Spin in a Charge Density Wave of 1-TaS
Seho Yi, Zhenyu Zhang, Jun-Hyung Cho
Two-dimensional layered transition metal dichalcogenide (TMDC) materials often exhibit exotic quantum matter phases due to the delicate coupling and competitions between the charge…
