Abstract

Abstract : Gold‐mediated exfoliation of ultralarge optoelectronically perfect monolayers with lateral dimensions up to ≈500 μm is reported. Electrical, optical, and X‐ray photo­electron spectroscopy characterization show that the quality of the gold‐exfoliated flakes is similar to that of tape‐exfoliated flakes. Large‐area flakes allow manufacturing of large‐area mono­layer transition metal dichalcogenide electronics.
