Abstract: We study a self-adjoint realization of a massless Dirac operator on a bounded connected domain \Omega\subset \mathbb{R}^2 which is frequently used to model graphene. In particular, we show that this operator is the limit, as M\to \infty , of a Dirac operator defined on the whole plane, with a mass term of size M supported outside \Omega .
