Research Abstract

The study of graphene and graphene-related materials is one of the most attractive areas of condensed-matter physics. Many studies have been done on graphene nanoribbons, which are one-dimensional derivatives of graphene. The other important graphene derivatives are graphene nanodisks, which have closed edges. I have explored rich physics of the electronic and magnetic properties of nanodisks starting from basic properties such as the band structure to applications to spintronics.
