| Abstract Scope |
High-quality 2D crystal growth has been studied with increasing interest. While the roll-to-roll processing has demonstrated success in growing and transferring large-area graphene samples, the layer-by-layer pattern transfer technology for a scalable and continuous fabrication of 2D heterostructures is unavailable for flexible substrate applications. To pattern 2D layers using conventional photolithography or e-beam lithography, poly(methyl methacrylate) (PMMA) or a similar polymer is introduced as a lithography mask. This exposure of 2D materials to polymers often introduces unwanted doping and reduced carrier mobility. In this work, we simulated the thermal additive manufacturing process to enable the continuous fabrication of 2D heterostructure on a flexible substrate. The key idea is to apply the thermal laser printing principle to the additive manufacturing process to precisely induce the local melting which ultimately results in the 2D materials etching. |
