2d-Material Dispersion and Printing: From Laboratory to Commercial Scale
… as a viable method for cost-effective and large-scale device fabrication. Many demonstrations are conducted on a small scale, but successful upscaling that would enable the ubiquitous uptake of printing for fabrication, has seldom been reported. The ability to produce 2d-materials dispersions on …
