Abstract Since Si‐based Moore's law is physically limited, 2D semiconductors are proposed as successors to continue shrinking the transistor size for more Moore electronics. However, limited by experimental technology bottlenecks, theoretical predicted superiorities of transistors over state‐of‐the‐art Si have been lacking concrete evidence a decade. In this review, recent exciting breakthroughs presented, including gate length miniaturization sub‐1 nm limit, electrode contact optimization...
