论文摘要
在Landauer运输形式主义中，我们证明，当将导线接触到不同的Sublattice地点时，两分组的电导零是可能的。特别是，我们研究了该理论在扶手椅配置中具有铅的石墨烯量子点的应用。在存在任何单位杂质的情况下，获得的电导取消是可靠的。
Within the Landauer transport formalism we demonstrate that conductance zeroes are possible in bipartite systems at half-filling when leads are contacted to different sublattice sites. In particular, we investigate the application of this theory to graphene quantum dots with leads in the armchair configuration. The obtained conductance cancellation is robust in the presence of any single-site impurity.
