Graphene and other layered materials, such as transition metal dichalcogenides, have rapidly established themselves exceptional building blocks for optoelectronic applications because of their unique properties atomically thin nature. The ability to stack them into van der Waals (vdWs) heterostructures with new functionality has opened a platform fundamental research device applications. Nevertheless, near-infrared (NIR) photodetectors based on semiconductors are rarely realized. In this...
High-performance thin film lithium niobate (LN) electro-optic modulators with low cost are in demand. Based on photolithography and wet etching, we experimentally demonstrate a LN Mach–Zehnder modulator 3 dB bandwidth exceeding 110 GHz, which shows the potential of boosting throughput reducing cost. The fabricated also exhibits comparable half-wave voltage-length product ∼2.37 V·cm, high extinction ratio >23 dB, propagation loss optical waveguides ∼0.2 dB/cm. Besides, six-level pulse...
This report presented the endemic status of schistosomiasis and analyzed data collected from national prevention control system surveillance program in People's Republic China 2022.

Abstract The recently discovered two-dimensional (2D) semimetal 1 T´-MoTe 2 exhibits colossal magnetoresistance and superconductivity, driving a strong research interest in the material’s quantum phenomena. Unlike typical hexagonal structure found many 2D materials, lattice has in-plane anisotropy. A full understanding of anisotropy is necessary for fabrication future devices which may exploit these topological properties, yet detailed study currently lacking. While angle resolved Raman...
