Strongly coupled magneto-exciton condensates in large-angle twisted double bilayer graphene
Qingxin Li, Yiwei Chen, LingNan Wei +15
Excitons, the bosonic quasiparticle emerging from Coulomb interaction between electrons and holes, will undergo a Bose-Einstein condensation(BEC) and transition into a superfluid s…
Gate control of 2D magnetism in tri- and four-layers /graphene heterostructures
Ping Wang, Fuzhuo Lian, Renjun Du +11
We conduct experimental studies on the electrical transport properties of monolayer graphene directly covered by a few layers of . We do not observe the expected magneti…
Ferroelectricity in twisted double bilayer graphene
Renjun Du, Jingkuan Xiao, Di Zhang +7
Two-dimensional ferroelectrics can maintain vertical polarization up to room temperature, and are, therefore, promising for next-generation nonvolatile memories. Although natural t…
Tunable ferroelectricity in hBN intercalated twisted double-layer graphene
Yibo Wang, Siqi Jiang, Jingkuan Xiao +10
Van der Waals (vdW) assembly of two-dimensional materials has been long recognized as a powerful tool to create unique systems with properties that cannot be found in natural compo…
Reversible Engineering of Topological Insulator Surface State Conductivity through Optical Excitation
Faji Xie, Zhen Lian, Shuai Zhang +13
Despite the broadband response, limited optical absorption at a particular wavelength hinders the development of optoelectronics based on Dirac fermions. Heterostructures of graphe…
Observation of ballistic avalanche phenomena in nanoscale vertical InSe/BP heterostructures
Anyuan Gao, Jiawei Lai, Yaojia Wang +13
Initiating impact ionization of avalanche breakdown essentially requires applying a high electric field in a long active region, hampering carrier-multiplication with high gain, lo…
Phase transition and anomalous scaling in the quantum Hall transport of topological insulator Sn-Bi1.1Sb0.9Te2S devices
Faji Xie, Shuai Zhang, Qianqian Liu +12
The scaling physics of quantum Hall transport in optimized topological insulators with a plateau precision of ~1/1000 e2/h is considered. Two exponential scaling regimes are observ…
Unusual suppression of the superconducting energy gap and critical temperature in atomically thin NbSe2
Ekaterina Khestanova, John Birkbeck, Mengjian Zhu +12
It is well known that superconductivity in thin films is generally suppressed with decreasing thickness. This suppression is normally governed by either disorder-induced localizati…
Stepwise quantized surface states and delayed Landau level hybridization in Co cluster-decorated BiSbTeSe2 topological insulator devices
Shuai Zhang, Li Pi, Rui Wang +16
In three-dimensional topological insulators (TIs), the nontrivial topology in their electronic bands casts a gapless state on their solid surfaces, using which dissipationless TI e…
Edge currents shunt the insulating bulk in gapped graphene
M. J. Zhu, A. V. Kretinin, M. D. Thompson +13
An energy gap can be opened in the electronic spectrum of graphene by lifting its sublattice symmetry. In bilayers, it is possible to open gaps as large as 0.2 eV. However, these g…
High Electron Mobility, Quantum Hall Effect and Anomalous Optical Response in Atomically Thin InSe
D. A. Bandurin, A. V. Tyurnina, G. L. Yu +16
A decade of intense research on two-dimensional (2D) atomic crystals has revealed that their properties can differ greatly from those of the parent compound. These differences are…
