Transition from insulator to metal induced by hybridized connection

摘要

A hybridized structure constructed by zigzag boron nitride nanoribbon and zigzag graphenennanoribbon is proposed, and their band structures and electronic transport properties are calculatednby applying first-principles calculations. The results show that the band gap of the hybridizednstructure can be tuned and transitions from insulator to metal can be realized by changing the unitnnumber of zigzag graphene nanoribbon. The currents with different spin polarization displayndifferent behavior. © 2010 American Institute of Physics. u0004doi:10.1063/1.3515921
