Optical Method Measures Graphene Quality
Graphene’s remarkable electrical and optical properties might lead to a new generation of computer chips, photovoltaic cells, and other devices. To make such devices practical, however, graphene has to be produced at an industrial scale, which means manufacturers need rapid ways to monitor the quality of their material. Now scientists in Taiwan have shown that a method long used for measuring the thickness of thin films provides . . .
