Summary

Two-dimensional (2D) materials such as graphene, hexagonal boron nitride (hBN) and the transition metal dichalcogenides exhibit a wide range of electronic and optical properties, making them platforms of interest for exploring fundamental phenomena and promising building blocks for next-generation electronic devices. One step in building such devices is the stacking of different layers of 2D materials to form a heterojunction. However, up to now such stacking procedure involves manual control that can take hours if not days and weeks of human labor. There is a need for an automated stacking process. In this invention Brookhaven researchers described stacking of 2D materials automatically, and specifically in an automated manner that minimizes the formation or aggregation of "bubble" contaminants, or other contaminating features between the layers of the stack or other defects.
