H2分子器件电子输运性质的模拟计算
Theoretical Study on the Electron Transport Properties of Hydrogen Molecular Device
【摘要】 理论计算H2分子在一维Pt链电极间形成的分子桥的伏安特性和电导,结果表明在两端金属电极作用下,H2分子的能隙减小,使得体系导电性能提高。
【Abstract】 The standard elastic electronic transport theory is introduced concisely;a theoretical study on transport properties of a H2 molecule bridged between one-dimensional Pt chains is carried out.The result shows that the conductance of the system is attributed to the reduction of the energy-gap of the H2 under the effect of metal electrodes.
