Unveiling the origin of unconventional moire ferroelectricity
Ruirui Niu, Zhuoxian Li, Xiangyan Han +13
Interfacial ferroelectricity emerges in heterostructures consisting of nonpolar van der Waals (vdW) layers, greatly expanding the scope of two dimensional ferroelectrics. In partic…
Anisotropic Infrared Response and Orientation-dependent Strain-tuning of the Electronic Structure in Nb2SiTe4
Fanjie Wang, Yonggang Xu, Lei Mu +6
Two-dimensional materials with tunable in-plane anisotropic infrared response promise versatile applications in polarized photodetectors and field-effect transistors. Black phospho…
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…
Evidences for the exciton gas phase and its condensation in monolayer 1T-ZrTe2
Yekai Song, Chunjing Jia, Hongyu Xiong +15
The excitonic insulator (EI) is a Bose-Einstein condensation (BEC) of excitons bound by electron-hole interaction in a solid, which could support high-temperature BEC transition. T…
Weak Antilocalization Effect up to ~ 120 K in the van der Waals Crystal Fe5-xGeTe2 with Near Room Temperature Ferromagnetism
Zhengxian Li, Kui Huang, Deping Guo +15
The weak antilocalization (WAL) effect is known as a quantum correction to the classical conductivity, which never appeared in two-dimensional magnets. In this work, we reported th…
Intrinsic disorder in graphene on transition metal dichalcogenide heterostructures
Matthew Yankowitz, Stefano Larentis, Kyounghwan Kim +8
The electronic properties of two-dimensional materials such as graphene are extremely sensitive to their environment, especially the underlying substrate. Planar van der Waals bond…
STM Spectroscopy of ultra-flat graphene on hexagonal boron nitride
Jiamin Xue, Javier Sanchez-Yamagishi, D. Bulmash +6
Graphene has demonstrated great promise for future electronics technology as well as fundamental physics applications because of its linear energy-momentum dispersion relations whi…
