We combined reflection difference microscopy, electron transport measurements, and atomic force microscopy to characterize the mechanical electrical anisotropy of few-layer black phosphorus. were able identify lattice orientations two-dimensional material construct suspended structures aligned with specific crystal axes. The approach allowed us probe anisotropic properties along each axis in separate measurements. measured Young's modulus phosphorus be 58.6 ± 11.7 27.2 4.1 GPa zigzag...
The topological materials have attracted much attention for their unique electronic structure and peculiar physical properties. ZrTe5 has host a long-standing puzzle on its anomalous transport properties manifested by unusual resistivity peak the reversal of charge carrier type. It is also predicted that single-layer two-dimensional insulator there possibly phase transition in bulk ZrTe5.

A kind of topological material, the type-II Weyl semimetal, was proposed recently where points emerge at contact electron and hole pockets, resulting in a highly tilted cone. In semimetals, Lorentz invariance is violated different type fermion generated that leads to intriguing physical properties.

The unique properties of two-dimensional (2D) materials make them promising candidates for chemical and biological sensing applications. However, most 2D material sensors suffer from extremely long recovery time due to the slow molecular desorption at room temperature.

Currently, optical or mechanical resonances are commonly used in microfluidic research. However, optomechanical oscillations by light pressure were not shown with liquids. This is because replacing the surrounding air water inherently increases acoustical impedance and hence, associated radiation losses. Here, we bridge between microfluidics optomechanics fabricating a hollow-bubble resonator liquid inside optically exciting vibrations 100 MHz rates using only mW optical-input power....

We report on a new chemical sensor based black phosphorus/molybdenum diselenide van der Waals hetero-junctions. Due to the atomically thin nature of two-dimensional (2D) materials, surface adsorption gas molecules can effectively modulate band alignment at junction interface, making device highly sensitive detector for adsorptions. Compared sensors made homogeneous nanomaterials, hetero-junction demonstrates considerably lower detection limit and higher sensitivity toward nitrogen dioxide....
