Researchers at the University of Manchester have made a breakthrough in the transfer of 2D crystals, paving the way for their commercialization in next-generation electronics. This technique, detailed in a recent Nature Electronics article, utilizes a fully inorganic stamp to create the cleanest and most uniform 2D material stacks to date.
The team, led by Professor Roman Gorbachev from the National Graphene Institute, employed the inorganic stamp to precisely "pick and place" 2D crystals into van der Waals heterostructures of up to eight individual layers within an ultra-high vacuum environment. This advancement resulted in atomically clean interfaces over extended areas, a significant leap forward compared to existing techniques and a crucial step towards the commercialization of 2D material-based electronic devices.
