First-principles calculations of double resonance Raman spectra for monolayer MoTe
Jianqi Huang, Huaihong Guo, Lin Zhou +5
Since double resonance Raman (DRR) spectra are laser-energy dependent, the first-principles calculations of DRR for two-dimensional materials are challenging. Here, the DRR spectru…
Ultrafast ferromagnetic fluctuations preceding magnetoelastic first-order transitions
Zhao Zhang, Yanna Chen, Dehong Yu +18
First-order magnetic transitions are of both fundamental and technological interest given that a number of emergent phases and functionalities are thereby created. Of particular in…
Dimer rattling mode induced low thermal conductivity in an excellent acoustic conductor
Ji Qi, Baojuan Dong, Zhe Zhang +19
A solid with larger sound speeds exhibits higher lattice thermal conductivity (k_{lat}). Diamond is a prominent instance where its mean sound speed is 14400 m s-1 and k_{lat} is 23…
Magnetic-field control of topological electronic response near room temperature in correlated Kagome magnets
Yangmu Li, Qi Wang, Lisa DeBeer-Schmitt +13
Strongly correlated Kagome magnets are promising candidates for achieving controllable topological devices owing to the rich interplay between inherent Dirac fermions and correlati…
Giant and Linear Magnetoresistance in Liquid Metals at Ambient Temperature
Xiaolin Wang, Feixiang Xiang, David Cortie +4
Disorder-induced magnetoresistance has been reported in a range of solid metals and semiconductors, however, the underlying physical mechanism is still under debate because it is d…
New two-dimensional phase of tin chalcogenides: candidates for high-performance thermoelectric materials
Baojuan Dong, Zhenhai Wang, Nguyen T. Hung +4
Tin-chalcogenides SnX (X = Te, Se and S) have been arousing research interest due to their thermoelectric physical properties. The two-dimensional (2D) counterparts, which are expe…
Observation of Various and Spontaneous Magnetic Skyrmionic Bubbles at Room-Temperature in a Frustrated Kagome Magnet with Uniaxial Magnetic Anisotropy
Zhipeng Hou, Weijun Ren, Bei Ding +12
Various and spontaneous magnetic skyrmionic bubbles are experimentally observed for the first time, at room temperature in a frustrated kagome magnet Fe3Sn2 with unixial magnetic a…
Double resonance Raman modes in mono- and few-layer MoTe
Huaihong Guo, Teng Yang, Mahito Yamamoto +7
We study the second-order Raman process of mono- and few-layer MoTe, by combining {\em ab initio} density functional perturbation calculations with experimental Raman spectrosc…
Microwave-driven Topological Resonant Excitations of Coupled Skyrmions
Han Wang, Yingying Dai, Teng Yang +2
We study nonlinear dynamics of coupled Skyrmions and present a method for manipulating topological resonant excitations by a dual-frequency microwave field. Thiele's equation is ex…
Strain-induced magnetism in MoS2 monolayer with defects
Peng Tao, Huaihong Guo, Teng Yang +1
The strain-induced magnetism is observed in single-layer MoS2 with atomic single vacancies from density functional calculations. Calculated magnetic moment is no less than 2muB per…
Skyrmion ground state and gyration of skyrmions in magnetic nanodisks without the Dzyaloshinsky-Moriya interaction
Yingying Dai, Han Wang, Peng Tao +3
We show by micromagnetic simulations that spontaneous skyrmion ground state can exist in Co/Ru/Co nanodisks without the Dzyaloshinsky-Moriya interaction (DMI), which can remain sta…
Doping effect on thermoelectric properties of MoS
Huaihong Guo, Teng Yang, Peng Tao +1
We systematically study thermoelectric properties of layered MoS by doping, based on Boltzmann transport theory and first-principles calculations. We obtain optimal doping regi…
