Scalable growth of two dimensional (2D) materials

2D growth

Centimeter sized boron nitride can be grown on and exfoliated from a single-crystalline rhodium thin film substrate. The findings have been highlighted in Science, 359, 649 (2018).
Growth on metals and transfer of two-dimensional material is a scalable route in device production schemes.
Monolayer hexagonal boron nitride (h-BN) and graphene are grown by chemical vapor deposition on metal surfaces. The photograph above shows a 4 inch wafer growth substrate in Zürich air on the balcony of building 36. The group of Thomas Greber succeeded to exfoliate and transfer centimetre sized single layer h-BN from a 4 inch wafer. This project is currently pursued within the European future and emerging technology flagship Graphene.
