We propose a non-Hermitian kagome-honeycomb photonic crystal platform for investigating the reconstruction of topological boundary and localized modes under the combined influence of lattice symmetry and non-Hermiticity modulation. The composite lattice supports both pseudospin and valley degrees of freedom, enabling p...

ABSTRACT Altermagnets host symmetry‐protected spin splitting without net magnetization, offering a new platform for spin‐dependent transport and optical responses. Here we demonstrate that bilayer altermagnets enable efficient and tunable second‐order injection photocurrents in the visible regime via interlayer couplin...

The International Roadmap for Devices and Systems (IRDS) has identified the tunnel field-effect transistor (TFET) as the most promising next-generation logic device that enables sustainable downscaling in driving voltage and power consumption. Demonstrating an acceptable sub-Boltzmann-limit ON current (namely I60, the...
