Symmetry-enforced topological band crossings in orthorhombic crystals: Classification and materials discovery
Andreas Leonhardt, Moritz M. Hirschmann, Niclas Heinsdorf +3
We identify all symmetry-enforced band crossings in nonmagnetic orthorhombic crystals with and without spin-orbit coupling and discuss their topological properties. We find that or…
Topological insulators in the NaCaBi family with large SOC gaps
Dexi Shao, Zhaopeng Guo, Xianxin Wu +4
By means of first-principles calculations and crystal structure searching techniques, we predict that a new NaCaBi family crystallized into the ZrBeSi-type structure (\ie $P6_{3}/m…
Direct evidence of electron-hole compensation for XMR in topologically trivial YBi
Shaozhu Xiao, Yinxiang Li, Yong Li +9
The prediction of topological states in rare earth monopnictide compounds has attracted renewed interest. Extreme magnetoresistance (XMR) has also been observed in several nonmagne…
Zone-folded longnitude acoustic phonons driving self-trapped state emission in colloidal CdSe nanoplate superlattice
Xinyu Sui, Xiaoqing Gao, Xianxin Wu +11
Colloidal cadmium chalcogenide nanoplates are two-dimensional semiconductors that have shown great application prospect for light-emitting technologies. Self-trapped state (STS), a…
Rashba-like spin splitting along three momentum directions in trigonal layered PtBi2
Ya Feng, Qi Jiang, Baojie Feng +14
Spin-orbit coupling (SOC) has gained much attention for its rich physical phenomena and highly promising applications in spintronic devices. The Rashba-type SOC in systems with inv…
Large Resistivity Reduction in Mixed-Valent CsAuBr Under Pressure
Pavel Naumov, Shangxiong Huangfu, Xianxin Wu +6
We report on high-pressure GPa resistivity measurements on the perovskite-related mixed-valent compound CsAuBr. The compounds high-pressure resistivity can be class…
Ultrafast electron calorimetry uncovers a new long-lived metastable state in 1T-TaSe mediated by mode-selective electron-phonon coupling
Xun Shi, Wenjing You, Yingchao Zhang +8
Quantum materials represent one of the most promising frontiers in the quest for faster, lightweight, energy efficient technologies. However, their inherent complexity and rich pha…
Topological Critical Materials of Ternary Compounds
Shengshan Qin, Congcong Le, Xianxin Wu +1
We review topological properties of two series of ternary compounds AMgBi (A=K, RB, Cs) and ABC with a hexagonal ZrBeSi type structure. The first series of materials AMgBi are pred…
Distinct surface and bulk charge density waves in ultrathin 1T-TaS2
Rui He, Junichi Okamoto, Zhipeng Ye +10
We employ low-frequency Raman spectroscopy to study the nearly commensurate (NC) to commensurate (C) charge density wave (CDW) transition in 1T-TaS2 ultrathin flakes protected from…
Visualizing Band Offsets and Edge States in Bilayer-Monolayer Transition Metal Dichalcogenides Lateral Heterojunction
Chendong Zhang, Yuxuan Chen, Jing-Kai Huang +5
Semiconductor heterostructures are fundamental building blocks for many important device applications. The emergence of two-dimensional semiconductors opens up a new realm for crea…
Dense network of one-dimensional mid-gap metallic modes in monolayer MoSe2 and their spatial undulations
Hongjun Liu, Lu Jiao, Fang Yang +9
We report the observation of a dense triangular network of one-dimensional (1D) metallic modes in a continuous and uniform monolayer of MoSe2 grown by molecular-beam epitaxy. High-…
