Assessing the defect tolerance of kesterite-inspired solar absorbers
Andrea Crovetto, Sunghyun Kim, Moritz Fischer +4
Various thin-film I-II-IV-VI photovoltaic absorbers derived from kesterite CuZnSn(S,Se) have been synthesized, characterized, and theoretically investigated in the…
Experimental and first-principles spectroscopy of CuSrSnS and CuBaSnS photoabsorbers
Andrea Crovetto, Zongda Xing, Moritz Fischer +7
The CuBaSnS (CBTS) and CuSrSnS (CSTS) semiconductors have been recently proposed as potential wide band gap photovoltaic absorbers. Although several measurements in…
Systematic investigation of the generation of luminescent emitters in hBN via irradiation engineering
Pooja C. Sindhuraj, José M. Caridad, Corné Koks +9
Hexagonal boron nitride (hBN), a two-dimensional (2D) material, garners interest for hosting bright quantum emitters at room temperature. A great variety of fabrication processes h…
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…
A room-temperature moiré interlayer exciton laser
Qiaoling Lin, Hanlin Fang, Yuanda Liu +10
Moiré superlattices in van der Waals heterostructures offer highly tunable quantum systems with emergent electronic and excitonic properties such as superconductivity, topological…
