Crystal structure and epitaxy of Bi2Te3 films grown on Si
Jihwey Park, Yeong-Ah Soh, G. Aeppli +5
We report comprehensive x-ray diffraction studies of the crystal structure and epitaxy of thin films of the topological insulator Bi2Te3 grown on Si (1 1 1). The films are single c…
Ultrafast Spontaneous Motion of Nanodroplets
Cunjing Lv, Chao Chen, Yin-Chuan Chuang +4
Making liquid droplets move spontaneously on solid surfaces is a key challenge in lab-on-chip and heat exchanger technologies. The best-known mechanism, a wettability gradient, doe…
Driving Droplets by Curvi-Propulsion
Cunjing Lv, Chao Chen, Yin-Chuan Chuang +4
How to make small liquid droplets move spontaneously and directionally on solid surfaces is a challenge in lab-on-chip technologies, DNA analysis, and heat exchangers. The best-kno…
Self-retracting motion of graphite micro-flakes: superlubricity in micrometer scale
Ze Liu, Jefferson Zhe Liu, Jiarui Yang +4
Through experimental study, we reveal superlubricity as the mechanism of self-retracting motion of micrometer sized graphite flakes on graphite platforms by correlating respectivel…
Graphite Nanoeraser
Ze Liu, Peter. Bøggild, Jia-rui Yang +5
We present here a method for cleaning intermediate-size (5~50nm) contamination from highly oriented pyrolytic graphite. Electron beam deposition causes a continuous increase of car…
Frictional scattering and frictional waveguides: achieving persistent superlubricity at high velocity on the nanoscale
Yilun Liu, Francois Grey, Quanshui Zheng
Nanomechanical devices can operate at much higher speeds than their macroscopic analogues, due to low inertia. For example, peak speeds >100m/s have been predicted for carbon nanot…
