Large‐sized, 2D single crystals of perylene are grown by both solution‐cast and physical vapor transport methods. The crystals have a atomically flat parallelogram morphology and the aspect ratios of the lateral extension compared to the thickness are up to 10 3 . The atomically flat feature leads to good interface contact, making a single‐crystal field‐effect transistor with higher mobility. The mobility of atomically flat crystals can be 10 3 –10 4 times higher than rough crystals.
