" ... A hexagonal array, like that found in a sheet of graphene, where atoms would be found at the... [+] vertices where lines meet. ... "
" ... Graphene has long been touted as the answer to all of the world's problems, with particular emphasis on more efficient electronics. While it shows great promise in this area, creating this two-dimensional material in the correct dimensions for such applications is proving to be a real challenge. Physical cutting of graphite blocks using fine diamond blades has been possible, but the isolation of individual layers of graphene in long, wide sections known as nanoribbons requires further isolation. ...
