Electronic Origin of Half-metal to Semiconductor Transition and Colossal Magnetoresistance in Spinel HgCr2Se4
Aiji Liang, Zhilin Li, Shihao Zhang +13
Half-metals are ferromagnets hosting spin-polarized conducting carriers and crucial for spintronics applications. The chromium spinel HgCr2Se4 represents a unique type of half-meta…
Persistent exchange splitting in a chiral helimagnet Cr1/3NbS2
Na Qin, Cheng Chen, Shiqiao Du +16
Using high-resolution angle-resolved photoemission spectroscopy (ARPES) and ab-initio calculation, we systematically investigate the electronic structure of the chiral helimagnet C…
Spectral Evidence for Unidirectional Charge Density Wave in Detwinned BaNiAs
Yucheng Guo, Mason Klemm, Ji Seop Oh +16
The emergence of unconventional superconductivity in proximity to intertwined electronic orders is especially relevant in the case of iron-based superconductors. Such order consist…
Observation of Γ-valley moiré bands and emergent hexagonal lattice in twisted transition metal dichalcogenides
Ding Pei, Binbin Wang, Zishu Zhou +19
Twisted van der Waals heterostructures have recently been proposed as a condensed-matter platform for realizing controllable quantum models due to the low-energy moiré bands with s…
Approaching a Minimal Topological Electronic Structure in Antiferromagnetic Topological Insulator MnBi2Te4 via Surface Modification
Aiji Liang, Cheng Chen, Huijun Zheng +12
The topological electronic structure plays a central role in the non-trivial physical properties in topological quantum materials. A minimal, hydrogen-atom-like topological electro…
Observation of Dimension-Crossover of a Tunable 1D Dirac Fermion in Topological Semimetal NbSiTe
Jing Zhang, Yangyang Lv, Xiaolong Feng +11
Condensed matter systems in low dimensions exhibit emergent physics that does not exist in three dimensions. When electrons are confined to one dimension (1D), some significant ele…
Direct Visualization and Manipulation of Tunable Quantum Well State in Semiconducting Nb2SiTe4
Jing Zhang, Zhilong Yang, Shuai Liu +12
Quantum well states (QWSs) can form at the surface or interfaces of materials with confinement potential. They have broad applications in electronic and optical devices such as hig…
Role of electron-phonon coupling in excitonic insulator candidate Ta2NiSe5
Cheng Chen, Xiang Chen, Weichen Tang +15
Electron-hole bound pairs, or excitons, are common excitations in semiconductors. They can spontaneously form and ``condense'' into a new insulating ground state -- the so-called e…
