摘要：
For the first time, a strong anisotropy of electrical conductance is established in graphene films with regular holes, graphene films with vertically aligned armchair carbon nanotubes (CNTs) seamlessly bonded to graphene, and monolayer pillared graphene films. Electrical conductance along the armchair direction is 3-7 times larger than that along the zigzag direction. Also, a prominent oscillation in electrical conductance along the armchair direction is first discovered. This effect is clearly manifested when the CNT length is increased by atomic layers. In this case, the electrical conductance oscillation can reach 80-90% and the oscillation frequency is equal to three.
