Ultra-Sensitive Extinction Measurements of Optically Active Defects in Monolayer MoS
Florian Sigger, Ines Amersdorffer, Alexander Hötger +12
We utilize cavity-enhanced extinction spectroscopy to directly quantify the optical absorption of defects in MoS generated by helium ion bombardment. We achieve hyperspectral i…
Combining experiments on luminescent centres in hexagonal boron nitride with the polaron model and ab initio methods towards the identification of their microscopic origin
Moritz Fischer, Ali Sajid, Jake Iles-Smith +10
The two-dimensional material hexagonal boron nitride (hBN) hosts luminescent centres with emission energies of 2 eV which exhibit pronounced phonon sidebands. We investigate the mi…
Spin-defect characteristics of single sulfur vacancies in monolayer
Alexander Hötger, Tomer Amit, Julian Klein +15
Single spin defects in 2D transition-metal dichalcogenides are natural spin-photon interfaces for quantum applications. Here we report high-field magneto-photoluminescence spectros…
