Resonant Ultrasound Spectroscopy for Irregularly-Shaped Samples and its Application to Uranium Ditelluride
Florian Theuss, Gregorio de la Fuente Simarro, Avi Shragai +11
Resonant ultrasound spectroscopy (RUS) is a powerful technique for measuring the full elastic tensor of a given material in a single experiment. Previously, this technique was limi…
Strong Magneto-Elastic Coupling in MnX (X = Ge, Sn)
Florian Theuss, Sayak Ghosh, Taishi Chen +3
We measure the full elastic tensors of MnGe and MnSn as a function of temperature through their respective antiferromagnetic phase transitions. Large discontinuities in the…
Anomalous transport due to Weyl fermions in the chiral antiferromagnets Mn, = Sn, Ge
Taishi Chen, Takahiro Tomita, Susumu Minami +9
The recent discoveries of strikingly large zero-field Hall and Nernst effects in antiferromagnets Mn, ( = Sn, Ge) have brought the study of magnetic topological states to…
Anomalous transverse response of CoMnGa and universality of the room-temperature ratio across topological magnets
Liangcai Xu, Xiaokang Li, Linchao Ding +6
The off-diagonal (electric, thermal and thermoelectric) transport coefficients of a solid can acquire an anomalous component due to the non-trivial topology of the Bloch waves. We…
Experimental evidence and control of the bulk-mediated intersurface coupling in topological insulator Bi2Te2Se nanoribbons
Zhaoguo Li, Ion Garate, Jian Pan +14
Nearly a decade after the discovery of topological insulators (TIs), the important task of identifying and characterizing their topological surface states through electrical transp…
Indications of the topological transport by the universal conductance fluctuations in the Bi2Te2Se microflakes
Zhaoguo Li, Yuze Meng, Jian Pan +6
Universal conductance fluctuations (UCFs) are extracted in the magnetoresistance responses in the bulk-insulating Bi2Te2Se microflakes. Its two-dimensional character is demonstrate…
Aging the Cu-doped Bi2Te3 crystals for the topological transport and its atomic tunneling-clustering dynamics
Taishi Chen, Qian Chen, Koen Schouteden +13
We report on the observation of the two-dimensional weak antilocalization in (Cu0.1Bi0.9)2Te3.06 crystals relying on measurements of the magnetoresistance in a tilted field. The de…
Shubnikov de Haas quantum oscillation of the surface states in the metallic Bismuth Telluride sheets
Taishi Chen, Junhao Han, Zhaoguo Li +8
Metallic Bi2Te3 crystalline sheets with the room-temperature resistivity of above 10 mΩ cm were prepared and their magnetoresistive transport was measured in a field of up to 9 Tes…
Two-dimensional universal conductance fluctuations and the electron-phonon interaction of topological surface states in Bi2Te2Se nanoribbons
Zhaoguo Li, Taishi Chen, Haiyang Pan +9
The universal conductance fluctuations (UCFs), one of the most important manifestations of mesoscopic electronic interference, have not yet been demonstrated for the two-dimensiona…
Two-step splitting the expandable graphite for few-layer graphene
Kaiming Liao, Wangfeng Ding, Yuyuan Qin +7
Few-layer graphene sheets are prepared by splitting the expanded graphites using a high-power sonication. Atomic-level quantitative scanning transmission electron microscopy (Q-STE…
Visualizing topological insulating Bi2Te3 quintuple layers on SiO2-capped Si substrates and its contrast optimization
Zhaoguo Li, Yuyuan Qin, Yuewen Mu +8
Thin Bi2Te3 flakes, with as few as 3 quintuple layers, are optically visualized on the SiO2-capped Si substrates. Their optical contrasts vary with the illumination wavelength, fla…
