"Researchers at Northwestern University’s McCormick School of Engineering have developed a graphene-based ink that could be sprayed onto substrates to make flexible electronics. While the research thus far has only extended to spraying 14-nanometer-thick layers to create precise patterns, the researchers believe that method they developed for creating the graphene-based ink could lead to flexible electronic devices in the future. ¶ While the graphene-based ink leads to patterns that are 250 times as conductive as previous attempts to print graphene-based electronic patterns, the paper doesn't discuss whether the material can be engineered to act as a semiconductor. Engineering a band gap into graphene remains a critical prerequisite for applying the material in electronics, and was a preoccupation for the Cornell team in its attempts to use graphene in flexible electronics." • #занимательная_физика - × × ×
