附注	electronic structures of coupled semiconductor quantum dots (qds) arranged as graphene hexagonal lattice are studied theoretically using the tight-binding method. in our calculations, the electrons can hop to the third-nearest-neighbors, and the overlap matrix as well as the multicenter integral are taken into account. the novel two-dimensional dirac-like electronic excitations in graphene are found in these artificial planar qd structures. the results provide the theoretical basis for searching dirac fermions in qd materials and have great significance for investigating and making semiconductor qd devices.
