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…
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…
