Van der Waals (vdW) heterostructures are composed of atomically thin layers assembled through weak (vdW) force, which have opened a new era for integrating materials with distinct properties and specific applications. However, few studies have focused on whether and how anisotropic materials affect heterostructure system. The study introduces anisotropic and isotropic materials in a heterojunction...
Strain is an effective strategy to modulate the electrical, optical, and optoelectronic properties of 2D materials. Conventional circular blisters could generate a biaxial stretching of 2D membranes with notable strain gradients along the hoop direction. However, such a deformation mode cannot be utilized to investigate mechanical responses of in‐plane anisotropic 2D materials, for example, black...
Anisotropic Mechanics and Phononics
In article number 2301959, Luqi Liu, Zhiping Xu, Zhong Zhang, and co‐workers develop a rectangular‐shaped bulge device to uniaxially stretch the suspended 2D materials and further serve as a promising platform to detect the orientation‐dependent mechanical and physical properties of anisotropic 2D materials. A typical anisotropic 2D material, black phosphorus, is...
Bismuth chalcohalides (BiSeI and BiSI), a class of superior light absorbers, have recently garnered great attention owing to their promise in constructing next‐generation optoelectronic devices. However, to date, the photodetection application of bismuth chalcohalides is still limited due to the challenge in controllable preparation. Herein, the synthesis of large‐scale quasi‐1D BiSeI nanowires via...
As an emerging two‐dimensional semiconductor, rhenium disulfide (ReS2) is renowned for its strong in‐plane anisotropy in electrical, optical, and thermal properties. In contrast to the electrical, optical, optoelectrical, and thermal anisotropies that are extensively studied in ReS2, experimental characterization of mechanical properties has largely remained elusive. Here, it is demonstrated that...
Magneto‐optical (MO) coupling incorporates photon‐induced change of magnetic polarization that can be adopted in ultrafast switching, optical isolators, mode convertors, and optical data storage components for advanced optical integrated circuits. However, integrating plasmonic, magnetic, and dielectric properties in one single material system poses challenges since one natural material can hardly...
Low‐dimensional semiconductors have attracted considerable attention due to their unique structures and remarkable properties, which makes them promising materials for a wide range of applications related to electronics and optoelectronics. Herein, the preparation of 1D Sb2Se3 nanowires (NWs) with high crystal quality via chemical vapor deposition growth is reported. The obtained Sb2Se3 NWs have triangular...
