Numerical and experimental study of thermally induced wavefront aberration in a direct-liquid-cooled Nd:YLF thin-disk laser gain module

The wavefront aberration induced by thermally in a direct-liquid-cooled Nd:YLF thin-disk laser gain module is investigated numerically with the laminar flow pattern. We find that the liquid layer plays the major role in causing of the wavefront aberration in the gain module. The...

Transport-of-intensity diffraction tomography with nonuniform axial sampling (TIDT-NAS)

Abstract Transport-of-intensity diffraction tomography (TIDT) extends the transport-of-intensity equation (TIE) from 2D phase retrieval to 3D refractive index (RI) tomography, enabling non-interferometric volumetric imaging under partially coherent illumination. By combining para...

Palladium-Catalyzed Site-Selective C–H Arylation of Arenes: Using Diaryl Disulfides as an Arylation Reagent

Abstract The development of site-selective C–H arylation of simple arenes is an urgent yet very challenging task. In particular, the meta-C–H activation of electron-deficient arenes is one of the most challenging substrates for selective functionalization and lacks efficient synt...

Broadband Transient Spectral Band Detection and Computation Based on 2D‐vdW Nano Device

ABSTRACT The ability to resolve optical signals with different wavelengths or colors is essential for a wide range of advanced photonic applications, such as wavelength‐division multiplexed multichannel optical communications and multiparameter intelligent sensing systems. Howeve...

Reconfigurable Logic Operation of MoTe 2 Homojunction Enabled by Staggered Double‐Sided Contacts

ABSTRACT Reconfigurable transistors capable of dynamically switching between p‐ and n‐type operations are highly desirable for compact and energy‐efficient logic circuits. Here, we demonstrate a reconfigurable MoTe 2 transistor enabled by a staggered double‐sided contact (SDC) ar...

Direct evaporation of single-crystal metal contacts for 2D semiconductors

Metal contacts remain one of the key bottlenecks in two-dimensional (2D) semiconductor electronics. We developed an atomic-scale step-by-step evaporation method to directly grow single-crystal metals on monolayer semiconductors with clean interfaces. This method accesses a distin...

Magnetoelectric BaTiO 3 /CoFe 2 O 4 Thin‐Film Meshes for Neuronal Differentiation

ABSTRACT Magnetoelectric composites offer a powerful route for remotely converting magnetic stimuli into local electrical cues, with promising biomedical applications in electrical stimulation. In strain‐mediated magnetoelectric heterostructures, however, efficient coupling depen...
