摘　　要：2D semiconductors offer a promising pathway to replace silicon in next-generation electronics.Among their many advantages,2D materials possess atomically-sharp surfaces and enable scaling the channel thickness down to the monolayer limit.However,these materials exhibit comparatively lower charge carrier mobility and higher contact resistance than 3D semiconductors,making it challenging to realize high-performance devices at scale.
