Scientists have mapped the strain in graphene, a 2-D sheet of carbon that is strong, flexible and can expand without breaking. Though the material has found its way into several applications, ranging from tennis rackets to smartphone touch screens, several obstacles are holding up further commercialization of graphene. One of these is the presence of defects that impose strain on graphene's lattice structure and adversely affects its electronic and optical properties.
