Catalogue of topological electrons and phonons in all allotropes of carbon
Qing-Bo Liu, Xiang-Feng Yang, Zhe-Qi Wang +3
Carbon, as one of the most common element in the earth, constructs hundreds of allotropic phases to present rich physical nature. In this work, by combining the ab inito calculatio…
Two-Dimensional Semiconducting Metal Organic Frameworks with Auxetic Effect, Room Temperature Ferrimagnetism, Chiral Ferroelectricity, Bipolar Spin Polarization and Topological Nodal Lines/Points
Xiangyang Li, Qing-Bo Liu, Yongsen Tang +7
Two-dimensional (2D) semiconductors integrated with two or more functions are the cornerstone for constructing multifunctional nanodevices, but remain largely limited. Here, by tun…
Realization of the Single-pair-Weyl Phonons with the Maximum Charge Number in Acoustic Crystals
Zhe-Qi Wang, Qing-Bo Liu, Xiang-Feng Yang +1
To observe the Weyl phonon (WP) with the maximum charge and to design a realistic material structure containing only single-pair-WPs have long been considered two challenges in the…
Symmetry-Enforced Weyl Phonons
Qing-Bo Liu, Yuting Qian, Hua-Hua Fu +1
In spinful electronic systems, time-reversal symmetry makes that all Kramers pairs at the time-reversal-invariant momenta are Weyl points (WPs) in chiral crystals. Here, we find th…
Proton-transfer Ferroelectricity / Multiferroicity in Rutile Oxyhydroxides
Menghao Wu, Tianci Duan, Chengliang Lu +3
Oxyhydroxide minerals like FeOOH have been a research focus in geology for studying the Earth interior, and also in chemistry for studying oxygen electrocatalysis activity. In this…
Possibility of Realizing Quantum Spin Hall Effect at Room Temperature in Stanene/Al2O3(0001)
Hui Wang, S. T. Pi, J. Kim +3
Two-dimensional quantum spin Hall (QSH) insulators with reasonably wide band gaps are imperative for the development of various innovative technologies. Through systematic density…
Conetronics in 2D Metal-Organic Frameworks: Double Dirac Cones, Magnetic Half Dirac Cones and Quantum Anomalous Hall Effect
Menghao Wu, Zhijun Wang, Junwei Liu +8
Based on recently synthesized Ni3C12S12 class 2D metal-organic frameworks, we predict electronic properties of M3C12S12 and M3C12O12, where M is Zn, Cd, Hg, Be, or Mg with no M orb…
