Transmission probabilities of graphene with square potential barrier are investigated by using the transfer matrix technique.The relations between the transmission probabilities and the incoming particle Fermi energies,the barrier width as well as the barrier height are revealed.These results are helpful in designing Nano devices based on graphene.
