The Promise of 2D Materials
All known materials have three dimensions, but those that are only one molecule thick are often referred to as two-dimensional materials for their lack of depth. Cornell University chemistry professor Michael G. Spencer—a Sigma Xi Distinguished Lecturer—studies these materials, including graphene, and spoke with American Scientist's managing editor Fenella Saunders about the great promise of such materials for use in electronics and other areas. He also spoke about the uses of thin films to advance betavoltaics, batteries powered by relatively harmless radioactive isotopes that produce electrons.
