A strategic review of recent progress, prospects and challenges of MoS₂-based photodetectors

Two-dimensional layered materials have emerged prominently in the past decade, largely being investigated fundamentally and practically. Their unique layered structure and atomic-scale thickness make them attractive with exclusive electrical and optical properties compared to their bulk counterparts. Molybdenum disulfide (MoS 2 ) is the most widely studied material in the family of transition metal dichalcogenides. The direct and variable...
