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

对于分子器件的研制，其功能分子的位置控制技术是必不可少的。在这项研究中，我们发现，通过控制STM探针的偏置电压，吸附在铋表面上的聚集态/扩散型铜酞菁(CuPc)分子可以在表面的任何点上被操纵。为了研究其作用机理，用密度泛函方法对其进行了分子轨道计算。通过将计算推广到类似的磁性分子，提出了一种利用近藤共振态的高导电性分子器件。

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.
