2D Vistas of flatland

摘要

"Two dimensions are golden," says Andre Geim of the University of Manchester, UK. Physics in one dimension is too simple to be satisfying, and three dimensions are complicated and messy. Two-dimensional "flatland" is just right, with just enough room for interesting and useful things to arise. "As a physicist, this is the dimension you would like to live in," says Geim.rnHe would say that. Geim was one of the team that in 2004 produced the first 2D material, sheets of carbon one atom thick known as graphene.
