Engineering defect density in chemical vapor deposited 2D MoS 2 for switchable optoelectronic devices
Deepak Kumar Sahu, Shreyasi Das, Saranya Das, Samit K. RayEngineering sulfur-vacancy by tailoring the precursor feedstock during growth and post-growth sulfur annealing controls carrier-trapping dynamics, thus switching the photoresponse from defect-dominated photosynaptic to photodetector operation.
