Detection and control of the Kondo resonance state induced by a magnetic single-molecular bridge by using STM

分子器件的发展离不开功能分子的位置控制技术。在本研究中，我们发现，通过控制STM探针的偏置电压，吸附在Bi表面上的酞菁铜（CuPc）分子的聚集/扩散在表面上的任何一点进行操纵。为了研究其作用机理，采用密度泛函理论方法进行了分子轨道计算。通过将计算推广到类似磁性分子，提出了一种利用近藤共振态的高导电分子器件。

For developments of a molecular device, position-controlling technique of its functional molecules is necessary. In this research, we have found that, by controlling bias voltage of STM probe, gathering/diffusing Copper-Phthalocyanine (CuPc) molecules adsorbed on the Bi surface is manipulated at any point on the surface. In order to investigate the working mechanism, the molecular-orbital calculation has been performed based on the DFT method. By extending the calculation to similar magnetic molecules, a highly electric-conductive molecular device utilizing Kondo resonance state is proposed.
