Interface Topology Driven Loss Minimization in Integrated Photonics: THz Ultrahigh‐Q Cavities and Waveguides

open access: yesAdvanced Materials, EarlyView.
Compact, robust, and ultralow‐loss on‐chip photonic devices are essential for densely integrated photonic chips. Here, the underlying radiation mechanism in topological valley edge states is unveiled and a new methodology of interface topology driven bandgap and wavevector engineering is proposed to thoroughly suppress their radiation losses, thereby ...

Semiconducting Pt Structures Stabilized on 2D MoS2 Crystals Enable Ultrafast Hydrogen Evolution

open access: yesAdvanced Materials, EarlyView.
The interaction of small Pt particles with 2D MoS2 crystals can stabilize bilayer Pt structures, with a semiconducting electronic structure. The semiconducting electronic structure of Pt bilayers constitutes the so far unexplored transition domain between the bulk‐like, metallic band structure of compact nanoparticles and the discrete atomic orbitals ...
