论文摘要
在桥梁配置中，单个石墨烯纳米替伯苯（GNR）位于沟槽上的皮仪精度，在AU（111）表面的两个单子飞机步骤之间。该GNR分子线在两个接触台阶之间的向下露台上采用了变形的构象。使用低温扫描隧道显微镜的差分电导DI/DV映射，可以证明如何通过其向下曲率在每个接触处切割沿GNR的电子离域化。它指出需要将导电纳米接触的背面带来支持，以保留前侧GNR平面构象。
In a bridge configuration, a single graphene nanoribbon (GNR) is positioned with a picometer precision over a trench in between two monoatomic steps on an Au(111) surface. This GNR molecular wire adopts a deformed conformation towards the down terrace in between the two contact step edges. Using differential conductance dI/dV mapping from a low-temperature scanning tunneling microscope, it is demonstrated how the electronic delocalization along GNR is cut at each contact by its down curvature. It points out the need to bring conductive nanocontacts backside of the support for preserving the front side GNR planar conformation.
