Room temperature coherent manipulation of single-spin qubits in silicon carbide with a high readout contrast
Qiang Li, Jun-Feng Wang, Fei-Fei Yan +16
Spin defects in silicon carbide (SiC) with mature wafer-scale fabrication and micro/nano-processing technologies have recently drawn considerable attention. Although room temperatu…
Nanoscale Probing of Broken-Symmetry States in Graphene Induced by Individual Atomic Impurities
Yu Zhang, Qi-Qi Guo, Si-Yu Li +1
Inherent symmetries of a system lead to multiple degeneracies of its energy spectra. Introducing individual atomic impurities can locally break these symmetries, which is expected…
A Movable Valley Switch Driven by Berry Phase in Bilayer Graphene Resonators
Yi-Wen Liu, Zhe Hou, Si-Yu Li +2
Since its discovery, Berry phase has been demonstrated to play an important role in many quantum systems. In gapped Bernal bilayer graphene, the Berry phase can be continuously tun…
Photoemission Spectroscopic Evidence for the Dirac Nodal Line in Monoclinic Semimetal SrAs
Y. K. Song, G. W. Wang, S. C. Li +8
Topological nodal-line semimetals with exotic quantum properties are characterized by symmetry-protected line-contact bulk band crossings in the momentum space. However, in most of…
STM Study of Quantum Hall Isospin Ferromagnetic States of Zero Landau Level in Graphene Monolayer
Si-Yu Li, Yu Zhang, Long-Jing Yin +1
A number of quantum Hall isospin ferromagnetic (QHIFM) states have been predicted in the relativistic zero Landau level (LL) of graphene monolayer. These states, especially the sta…
Valley Polarization and Inversion in Strained Graphene via Pseudo-Landau Levels, Valley Splitting of Real Landau Levels and Confined States
Si-Yu Li, Ying Su, Ya-Ning Ren +1
It is quite easy to control spin polarization and spin direction of a system via magnetic fields. However, there is no such a direct and efficient way to manipulate valley pseudosp…
Experimental identification of critical condition for drastically enhancing thermoelectric power factor of two-dimensional layered materials
Junwen Zeng, Xin He, Shi-Jun Liang +16
Nano-structuring is an extremely promising path to high performance thermoelectrics. Favorable improvements in thermal conductivity are attainable in many material systems, and the…
Mimicing the Kane-Mele type spin orbit interaction by spin-flexual phonon coupling in graphene devices

The electron transport between two zigzag graphene nanoribbons (ZGNRs) connected by carbon atomic chains has been investigated by the nonequilibrium Green's function method combine…
Experimental verification of the surface termination in the topological insulator TlBiSe using core-level photoelectron spectroscopy and scanning tunneling microscopy
Kenta Kuroda, Mao Ye, Eike F. Schwier +10
The surface termination of the promising topological insulator TlBiSe has been studied by surface and bulk sensitive probes. Our scanning tunneling microscopy has unmasked fo…
Pressure induced topological quantum phase transition in Sb_2Se_3
Wei Li, Xin-Yuan Wei, Jian-Xin Zhu +2
Based on the first-principles band structure calculations, we investigate the effects of hydrostatic pressure on the conventional insulator (CI) Sb_2Se_3 and predict that it underg…
