For layered 2D materials, robotics produces cleaner interfaces between stacked sheets

Researchers at NYU Tandon School of Engineering — led by Associate Professor Davood Shahrjerdi — and Brookhaven National Laboratory have developed a novel method for assembling ultra-thin materials called graphene heterostructures. Using a robotic system, they combined mechanical force and heat to create exceptionally clean, large-scale stacks of atom-thick layers measuring up to 7.5 square millimeters. The new technique, which removes contamination more effectively than traditional methods, represents a significant advance for manufacturing next-generation electronic devices and batteries using these advanced materials.
