Fano Interference in a Single-Molecule Junction
Yiping Ouyang, Rui Wang, Deping Guo +13
Trends of miniaturized devices and quantum interference electronics lead to the long desire of Fano interference in single-molecule junctions, here, which is successfully demonstra…
Lateral Heterojunction Sb2Te3/Bi2Te3 and its topological transport
Fucong Fei, Qianjin Wang, Zhongxia Wei +9
A lateral heterojunction of topological insulator Sb2Te3/Bi2Te3 was successfully synthesized using a two-step solvothermal method. The two crystalline components were separated wel…
Enhanced quantum coherence in graphene caused by Pd cluster deposition
Yuyuan Qin, Junhao Han, Guoping Guo +8
We report on the unexpected increase in the dephasing lengths of a graphene sheet caused by the deposition of Pd nanoclusters, as demonstrated by weak localization measurements. Th…
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…
Visualizing plasmon coupling in closely-spaced chains of Ag nanoparticles by electron energy loss spectroscopy
Fengqi Song, Tingyu Wang, Xuefeng Wang +8
Anisotropic plasmon coupling in closely-spaced chains of Ag nanoparticles was visualized using the electron energy loss spectroscopy in a scanning transmission electron microscope.…
Calibrating the atomic balance by carbon nanoclusters
Fengqi Song, Xuefeng Wang, Rebecca C. Powles +9
Carbon atoms are counted at near atomic-level precision using a scanning transmission electron microscope calibrated by carbon nanocluster mass standards. A linear calibration curv…
Experimental evidence on the Altshuler-Aronov-Spivak interference of the topological surface states in the exfoliated Bi2Te3 nanoflakes
Yuyuan Qin, Zhaoguo Li, Fengqi Song +10
Here we demonstrate the Altshuler-Aronov-Spivak (AAS) interference of the topological surface states on the exfoliated Bi2Te3 microflakes by a flux period of h/2e in their magnetor…
Experimental observation of nanojets formed by heating the PbO-coated Pb clusters
Fengqi Song, Min Han, Minda Liu +3
In this article, we will present the first experimental observation of nanojets formed by heating PbO-coated Pb clusters, which has been predicted theoretically by M. Moseler and U…
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…
