The invention discloses a megasonically exfoliated two-dimensional (2D) nanomaterial ink. The megasonically exfoliated 2D nanomaterial ink is then aerosol-jet printed (AJP) onto printed graphene electrodes to achieve all-AJP, flexible photodetectors. The 2D nanomaterial AJP ink is designed with terpineol, a high boiling point solvent, which enables a highly ordered thin-film morphology and also improves the photogenerated charge transport. After printing, the photodetectors are photonically annealed, which provides quasi-ohmic contacts and photoactive channels with responsivities that outperform previously reported all-printed visible photodetectors by over 3 orders of magnitude. Megasonic exfoliation coupled with AJP allows the superlative optoelectronic properties of ultrathin nanosheets to be utilized in the scalable additive manufacturing of mechanically flexible optoelectronics.
