Interfacial imperfections induced by substrate and environment are known to potentially reduce the electronic and optical properties of semiconducting transition metal dichalcogenides [1]. On the other hand, deterministically induced point defects induced by focused ion beams are promising candidates to serve as quantum emitters with well controlled energies that can be positioned with nm resolution [2]. Here, we investigate signature of disorder, imperfections and lattice defects one the properties of semiconducting 2D materials by a combination of scanning probe methods, optical and Raman spectroscopy.
