Covalent Patterning of 2D MoS(2)

The development of an efficient method to patterning 2D MoS(2) into a desired topographic structure is of particular importance to bridge the way towards the ultimate device. Herein, we demonstrate a patterning strategy by combining the electron beam lithography with the surface covalent functionalization. This strategy allows us to generate delicate MoS(2) ribbon patterns with a minimum feature size of 2 μm in a high throughput rate. The patterned monolayer MoS(2) domain consists of a spatially well‐defined heterophase homojunction and alternately distributed surface characteristics, which holds great interest for further exploration of MoS(2) based devices.
