非弹性隧穿中的协同效应

Cooperative effects in inelastic tunneling

Michael Galperin, Abraham Nitzan

摘要:

近年来,人们对分子导电中分子间效应的几个方面进行了研究。这些实验和理论研究,在几个设置的分子传导结,集中在电流-电压特性,通常是由这种结的弹性传输特性为主。在本文中,我们解决合作分子间的非弹性隧穿信号计算简单的通用模型,这样的系统。我们发现,即使直接分子间相互作用可以忽略不计,非弹性光谱中的峰高可能会受到这种合作效应的影响。这一发现表明,将实验结果与单分子结的计算结果进行比较时应该小心。

英文摘要:

Several aspects of intermolecular effects in molecular conduction have been studied in recent years. These experimental and theoretical studies, made on several setups of molecular conduction junctions, have focused on the current-voltage characteristic that is usually dominated by the elastic transmission properties of such junctions. In this paper we address cooperative intermolecular effects in the inelastic tunneling signal calculated for simple generic models of such systems. We find that peaks heights in the inelasticspectrum may be affected by such cooperative effects even when direct intermolecular interactions can be disregarded. This finding suggests that comparing experimental results to calculations made on single-molecule junctions should be done with care.
