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…
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…
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…
