Physicists reveal how layers and twist affect graphene’s photoconductivity
New research led by FSU assistant professor of physics Guangxin Ni reveals the optoelectronic properties of twisted bilayer graphene. Credit: Guangxin Ni When it comes to conductive nanomaterials, graphene, which is stronger and lighter than steel and more conductive than copper, has been shown to be an excellent choice for a wide range of technologies. Physicists are working to learn…
