"2D transistors with 3D raised contacts using van der Waals peeling... multilayer black phosphorus transistor channel gradually reduced to monolayer thickness without degradation, retaining multilayer contact region... homo-junctions and -superlattices based on 2D semiconductors BP, GeAs, InSe (indium selenide) and GaSe (gallium selenide)... maintaining contact region thickness since phosphorus carrier mobility drops sharply when reducing body thickness... wearables and smaller electronics, organic and perovskite monolayers"
