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...
The group IV-VI compound tin selenide (SnSe) has recently attracted particular interest due to its unexpectedly low thermal conductivity and high power factor shows great promise for thermoelectric applications. With an orthorhombic lattice structure, SnSe displays intriguing anisotropic properties the symmetry of puckered in-plane structure. When materials, such as SnSe, have decreased dimensionality, their conversion efficiency may be improved increased conductivity. Therefore, it is...
Tungsten ditelluride (WTe2) is a semi-metallic layered transition metal dichalcogenide with stable distorted 1T phase. The reduced symmetry of this system leads to in-plane anisotropy in various materials properties. We have systemically studied the Raman modes few-layer and bulk WTe2 by angle-dependent polarized spectroscopy (ADPRS). Ten are clearly resolved. Their intensities show periodic variation sample rotating. identify symmetries detected quantitatively analyzing ADPRS results based...
We systematically study the high-resolution and polarized Raman spectra of multilayer (ML) ${\mathrm{MoTe}}_{2}$. The layer-breathing (LB) shear (C) modes are observed in ultralow-frequency region, which used to quantitatively evaluate interlayer coupling ML ${\mathrm{MoTe}}_{2}$ based on linear chain model, only nearest is considered. three different substrates verify negligible substrate effect phonon frequencies Ten excitation energies measure high-frequency $N$-layer ($N\mathrm{L}...
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...
WTe<sub>2</sub>, which is an orthorhombic semimetal crystallized in Td phase, exhibts distinct in-plane anisotropy. The Raman modes depict different anisotropic response by rotating the incident polarization under excitation wavelengths.

The K-Nearest Neighbor (KNN) algorithm is a classical machine learning algorithm. Most KNN algorithms are based on single metric and do not further distinguish between repeated values in the range of K values, which can lead to reduced classification effect thus affect accuracy fault diagnosis. In this paper, hybrid metric-based proposed calculate composite containing distance direction information test samples, improves discriminability samples. experiments, (HM-KNN) paper compared...
Monolayer MoS2 is synthesized on hexagonal boron nitride (h-BN) flakes with a simple, high-yield method. h-BN exhibits improved optical quality. Combining the theoretical and experimental analysis, it concluded that enhanced photoluminescence Raman intensities of monolayer probably originate from relatively weak doping effect substrate rather than interference effect. As service to our authors readers, this journal provides supporting information supplied by authors. Such materials are peer...
Optical refractive index (RI) sensors, with the advantages of fast response, resistance to electromagnetic interference, and more options for signal collection, are widely used in biological fields. Compared metallic nanoparticle RI sensors based on localized surface plasmon resonance (SPR), nonmetallic nanomaterial leaky resonant scattering have high sensitivity, large sensing volume, good reliability, suitability biosensing. However, so far studies less reported. In this work, we study...

However, canonical PSO algorithms fail balance exploration exploitation, resulting reduced accuracy stability, decreasing control effectiveness of In order address this issue, a balanced (BPSO) proposed, which achieves better performance by balancing algorithm’s exploitation capabilities. BPSO solving...
