The E1 Semi-automatic 2D Material Transfer Stage, developed by ABN, is a high-precision manipulation platform tailored for fundamental research on two-dimensional (2D) materials, pre-fabrication of devices and teaching experiments. It is mainly used to stably and controllably transfer 2D materials such as Graphene, Transition Metal Dichalcogenides (TMDs) and hexagonal Boron Nitride (hBN) from growth substrates or intermediate carriers onto target substrate surfaces.
Adopting a design that combines electric precision motion with manual fine adjustment, the equipment delivers excellent alignment accuracy and transfer yield, while featuring a compact structure and cost-effectiveness. Compared with fully automatic systems, this semi-automatic solution boasts remarkable advantages in operational flexibility, maintenance cost and teaching applicability. It is an ideal choice for university laboratories, research institutes, as well as research teams engaged in elementary to intermediate 2D material studies.
