New Technique for Building Ultra-Thin Materials Promises Quantum Breakthrough

Topic: Physics

Scientists from Southampton and Singapore have developed a new method to build ultra-thin materials that could be used in quantum technology. The technique uses natural mineral muscovite instead of sticky polymers, making the process cleaner and cheaper.

Scientists at the University of Southampton and the National University of Singapore have created a new way to stack atomically thin materials together. This method is called ultra-clean manufacturing of 2D heterostructures.

These materials are just a few atoms thick and could be used in quantum technology and electronics. However, current methods for building these materials use sticky synthetic polymers that leave behind microscopic residues. These residues can contaminate the tiny structures and disrupt their performance.

The research team used natural mineral muscovite, or mica, to stack the atomically thin materials together instead of using polymers. Their findings showed that replacing polymers with mica makes the material atomically flat and offers better surfaces for precisely stacking the atomic layers on top of each other.

Lead author Dr. Makars Šiškins said, 'Our new method allows us to precisely align the layers to create complex structures that were previously too hard to make.' He added that this level of precision is vital for quantum material research, where even a tiny amount of contamination can obscure the results.
