PtTe2 interface engineering for enhanced near‐infrared photoresponse in black silicon photodetectors
InfoMat, EarlyView.Highly responsive near‐infrared (NIR) photodetectors are essential for advanced photoelectric systems. In this work, a high‐responsivity NIR photodetector is developed by integrating a PtTe2/black silicon (B‐Si) heterostructure into a Si p‐i‐n diode, where B‐Si introduces sub‐bandgap defect states to enhance NIR absorption and the PtTe2 layer induces ...

A Min–Max Relation on Dicuts and Dijoins in Weighted Chordal Digraphs
Journal of Graph Theory, EarlyView.ABSTRACT In a digraph, a dicut is a cut where all the arcs cross in one direction. A dijoin is a subset of arcs that intersects every dicut. Edmonds and Giles conjectured that in a weighted digraph, the minimum weight of a dicut is equal to the maximum size of a packing of dijoins. This has been disproved. However, the unweighted version conjectured by

Laser &Photonics Reviews, EarlyView.This review summarizes recent progress in meta‐photonics with a focus on bound states in the continuum (BICs) as a powerful platform for light confinement and control. It covers fundamental concepts, design strategies across optical regimes, symmetry breaking for practical quasi‐BICs, tunable and AI‐assisted BIC devices, and emerging applications in ...

Dipole‐Quadrupole Model and Multipole Analysis of Resonant Membrane Metasurfaces
Laser &Photonics Reviews, EarlyView.Membrane metasurfaces, arrays of holes in a dielectric membrane, are appealing because they require no substrate and allow access to resonant near‐fields. However, developing a comprehensive theoretical description for them remains challenging. We introduce a semi‐analytical dipole‐quadrupole approach to analyze their resonant spectra at arbitrary ...

Controlling Collective Quasiparticle Dynamics Beyond Decoherence in Topological Interfaces
Laser &Photonics Reviews, EarlyView.Gold nanoparticles placed above a deformed honeycomb plasmonic crystal couple to a chiral topological interface mode. The pseudospin‐split bands ψ+/ ψ− encode spin‐momentum locking, so emitters radiate directionally along the domain wall and share a common phase.
