利用扫描隧道显微镜的隧穿电流,我们证明了一个4-乙酰联苯分子沿着吸附在Si(100)-(2 × 1)表面的二聚体行上,可以在两种稳定的构象之间可逆地转换.由密度泛函理论计算支持的实验表明,分子通过开关选择性地钝化和去钝化硅表面上的悬挂键对,为基于悬挂键的原子级电路的逻辑输入开辟了新的途径。
We demonstrate that a single 4-acetylbiphenyl molecule adsorbed along the dimer row of a Si(100)-(2 X 1) surface can be reversibly switched between two stable conformations using the tunneling current of a scanning tunneling microscope. The experiment supported by density functional theory calculations demonstrates that the molecule by switching selectively passivates and depassivates a dangling-bond pair on the silicon surface, opening new routes for the logical input in dangling-bond-based atomic-scale circuits.
