Micro-patterned deposition of MoS2 ultrathin-films by a controlled droplet dragging approach

Abstract Micropatterning of transition metal dichalcogenide (TMDC) ultrathin-films and monolayers has been demonstrated by various multi-step approaches. However, directly achieving a patterned growth of TMDC films is still considered to be challenging. Here, we report a solution-based approach for...
