Atomic-scale Visualization of Electronic Fluid Flow
Xiaolong Liu, Yi Xue Chong, Rahul Sharma +1
The most essential characteristic of any fluid is the velocity field v(r) and this is particularly true for macroscopic quantum fluids. Although rapid advances have occurred in qua…
Nanoscale probing of image-potential states and electron transfer doping in borophene polymorphs
Xiaolong Liu, Luqing Wang, Boris I. Yakobson +1
Using field-emission resonance spectroscopy with an ultrahigh vacuum scanning tunneling microscope, we reveal Stark-shifted image-potential states of the v_1/6 and v_1/5 borophene…
Severe Dirac Mass Gap Suppression in Sb_2Te_3-based Quantum Anomalous Hall Materials
Yi Xue Chong, Xiaolong Liu, Rahul Sharma +5
Quantum anomalous Hall (QAH) effect appears in ferromagnetic topological insulators (FMTI) when a Dirac mass gap opens in the spectrum of the topological surface states (SS). Unacc…
Stable Aqueous Dispersions of Optically and Electronically Active Phosphorene
Joohoon Kang, Spencer A. Wells, Joshua D. Wood +7
Understanding and exploiting the remarkable optical and electronic properties of phosphorene require mass production methods that avoid chemical degradation. While solution-based s…
Point Defects and Grain Boundaries in Rotationally Commensurate MoS2 on Epitaxial Graphene
Xiaolong Liu, Itamar Balla, Hadallia Bergeron +1
With reduced degrees of freedom, structural defects are expected to play a greater role in two-dimensional materials in comparison to their bulk counterparts. In particular, mechan…
Rotationally Commensurate Growth of MoS2 on Epitaxial Graphene
Xiaolong Liu, Itamar Balla, Hadallia Bergeron +3
Atomically thin MoS2/graphene heterostructures are promising candidates for nanoelectronic and optoelectronic technologies. Among different graphene substrates, epitaxial graphene…
