金属-有机界面的电子输运

Electron transport across a metal-organic interface

Kurt Stokbro, Søren Smidstrup

摘要:

利用非平衡格林函数和密度泛函理论(NEGF-DFT)模拟了Au(111)-并五苯界面的电子输运,计算了偏压依赖的电子输运.我们发现,电接触电阻主要由在界面处形成的肖特基势垒,并表明,传统的半导体传输模型跨越肖特基势垒需要修改,以描述模拟数据。我们提出了一个传统的肖特基势垒输运模型的扩展,它可以描述我们的模拟结果和合理化最近的实验数据。

英文摘要:

We simulate the electron transport across the Au(111)-pentacene interface using non-equilibrium Green's functions and density-functional theory (NEGF-DFT), and calculate the bias-dependent electron transmission. We find that the electrical contact resistance is dominated by the formation of a Schottky barrier at the interface, and show that the conventional semiconductor transport models across Schottky barriers need to be modified in order to describe the simulation data. We present an extension of the conventional Schottky barrier transport model, which can describe our simulation results and rationalize recent experimental data.
