Deskripsi
The optical and electronic properties of semiconducting transition metal dichalcogenides are strongly dependent on native defects within their crystal lattice. Here, the authors use transient spectroscopy to identify defect-related deep levels in the bandgap of MoS2, WS2 and their alloys.
