High Purcell enhancement in all-TMDC nanobeam resonator designs with active monolayers for nanolasers
Felix Binkowski, Aris Koulas-Simos, Fridtjof Betz +9
We propose a nanobeam resonator incorporating an active monolayer, designed to achieve a high Purcell enhancement. The resonator is fully composed of transition-metal-dichalcogenid…

Probing Noncentrosymmetric 2D Materials by Fourier Space Second Harmonic Imaging
Lucas Lafeta, Sean Hartmann, Bárbara Rosa +3
The controlled assembly of twisted 2D structures requires precise determination of the crystal orientation of their component layers. In the established procedure, the second-harmo…
