Graphene superstrates for metamaterials
, 2010 The electromagnetic properties of a photonic metamaterial are dramatically modified by a graphene monolayer superstrate. The strong polarizability of the graphene layer combined with the Fano-type, resonant plasmonic modes supported by the metamaterial ...

Advanced Materials, Volume 38, Issue 31, 2 June 2026.Triply‐twinned architected lattices transform deformation from bending to stretching of struts, delivering up to threefold increases in stiffness and strength across polymeric and metallic systems. High‐resolution synchrotron XCT and image‐based simulations reveal how meta‐grain architecture, defects, and AM build orientation govern failure pathways ...

A Colloidal Quantum Dot Thermistor and Bolometer
Advanced Materials, Volume 38, Issue 32, 8 June 2026.This work introduces colloidal quantum dot thermistors employing a potential barrier structure to tune the activation energy of transport and hence the temperature coefficient of resistance (TCR). Upon integration with plasmonic absorbers, the CQD‐based bolometer device enables room‐temperature wavelength‐selective photodetection across the mid‐ to ...

Multi‐Mode Deep Strong Coupling in a Multi Quantum Well Fabry–Perot Cavity
Advanced Optical Materials, Volume 14, Issue 21, 5 June 2026.Multi‐mode deep‐strong coupling is demonstrated in a 166‐well heterostructure that acts as a Fabry–Perot cavity. Even cavity modes couple strongly to the cyclotron resonance, producing large vacuum Rabi splittings and a rich polaritonic spectrum captured by a full Hopfield model.

Optical Pulling Force on Gold Mie Particles via Germanium and Aluminum‐Based Structures
Advanced Photonics Research, Volume 7, Issue 6, June 2026.This work demonstrates a novel approach to generate optical pulling force on gold Mie objects of two different shapes and studies the effects for different object sizes, incident angles, and the aluminum tetrahedra separation. Using rectangular germanium blocks combined with aluminum tetrahedra, optical pulling force (OPF) is achieved over a broad ...
