MIT researchers have found a simple solution to protect graphene from performance-impairing wrinkles and contaminants.
Graphene is an atom-thin material that holds promise for making next-generation electronics. Researchers are exploring possibilities for using the exotic material in circuits for flexible electronics and quantum computers, and in a variety of other devices.
But removing the fragile material from the substrate it’s grown
In a paper published in Nature Communications, the researchers describe a fabrication technique that applies a wax coating to a graphene sheet and heats it up. Heat causes the wax to expand, which smooths out the graphene to reduce wrinkles. Moreover, the coating can be washed away without leaving behind much residue.
In experiments, the researchers’ wax-coated graphene performed
