The deep ultraviolet photodetectors based on 2D h-BN show a high on/off ratio of >10<sup>3</sup> and good spectral selectivity.
Polar domains arise in insulating ferroelectrics when free carriers are unable to fully screen surface-bound charges. Recently discovered binary and ternary polar metals exhibit broken inversion symmetry coexisting with electrons that might be expected suppress the electrostatic driving force for domain formation. Contrary this expectation, we report first direct observation of single crystals metal Ca3Ru2O7. By a combination mesoscale optical second-harmonic imaging atomic-resolution...
Catalyst-free growth of wafer-scale h-BN few-layers is realized on sapphire substrates by the combination surface nitridation and N<sup>+</sup> sputtering.
Recently, the deep ultraviolet (DUV) photodetectors fabricated from two-dimensional (2D) hexagonal boron nitride (h-BN) layers have emerged as a hot research topic. However, existing studies show that h-BN-based relatively poor performance. In this work, C doping is utilized to modulate properties of h-BN and improve performance photodetectors.

Regulating magnetism of a metal-organic framework (MOF) is highly desirable in magnetoelectric devices. Single-crystalline MOFs [(CH3)2NH2]2[FeIIIFe2-xIICoxII(HCOO)9] (x = 0, 0.2, 0.3, 0.6) with an unprecedented (412·63)1(49·66)2 topology were synthesized. These exhibit distinct antiferromagnetism, and the Néel temperature (TN) changes from 32.8 to 29.0 K increasing x. After field cooling above TN 2 K, these demonstrate giant exchange bias (EB) featured by significant vertical simultaneous...
As an effective means of solving collision problems caused by the limited perspective on board, cooperative roadside system is gaining popularity. To improve vehicle detection abilities in such online safety systems, this paper, we propose a novel multi-sensor multi-level enhanced convolutional network model, called architecture (MME-YOLO), with consideration hybrid realistic scene scales, illumination, and occlusion. MME-YOLO consists two tightly coupled structures, i.e., inference head...

Spin-triplet superconductivity in Sr2RuO4 has attracted enormous interest. Like other unconventional superconductors, is close proximity to magnetic instability. Undoped exhibits incommensurate antiferromagnetic (AFM) fluctuations, which can evolve into static, short-range AFM order via Ti doping. Moreover, weak ferromagnetic (FM) coupling also been suggested by NMR/neutron scattering experiments and studies on Ca2−xSrxRuO4 Sr2−yLayRuO4, implying orbital dependent magnetism. We report bulk...

We report the electronic and magnetic phase diagram of Ca${}_{3}$(Ru${}_{1\ensuremath{-}x}$Ti${}_{x}$)${}_{2}$O${}_{7}$. With Ti doping, system evolves from a quasi-two-dimensional metal with ferromagnetic (FM) bilayers coupled antiferromagnetically along $c$ axis (AFM-b) for $x=0$, to weakly localized state $0<x<0.05$, finally Mott insulator G-type antiferromagnetic (G-AFM) order $x\ensuremath{\ge}0.05$. The switching AFM-b G-AFM occurs in near $x=0.03$. show that such transition is...
We report an unusual nearly ferromagnetic heavy-mass state with a surprisingly large Wilson ratio ${R}_{w}$ (e.g., ${R}_{w}\ensuremath{\sim}700$ for $x=0.2$) in double layered ruthenates ${({\text{Sr}}_{1\ensuremath{-}x}{\text{Ca}}_{x})}_{3}{\text{Ru}}_{2}{\text{O}}_{7}$ $0.08<x<0.4$. This does not evolve into long-range ferromagnetically ordered despite considerably strong correlations, but it freezes cluster-spin glass at low temperatures. In addition, evidence of non-Fermi-liquid...
