Diamondiyne: A 3D Carbon Allotrope With Mixed sp–sp 3 Hybridization

ABSTRACT The creation of carbon allotropes is synthetically highly challenging, but their practical significance to science and technology cannot be underestimated. Here, we report the synthesis of a new carbon allotrope, diamondiyne, which is the second known one (after diamond)...

Polaritonic Materials: A Comparative Study on the Relaxation Kinetics in Fabry–Perot versus Plasmonic Cavities

ABSTRACT Strong exciton–photon coupling results in the formation of hybrid light–matter states whose relaxation dynamics often experience a bottleneck due to a large manifold of dark states. This bottleneck results in dynamics like those of the uncoupled material, hampering the o...
