我们证明，如果适当地描述分子电子学，势垒图可以定量地再现电流，并描述Song等人制造的分子晶体管中的轨道选通。作者声明：[H.Song，Y.Kim，Y.H.Jang，H.Jeong，MA.李瑞德，《自然》462(2009)1039]。基于我们的结果，我们证明了(I)测量的电流代表单个分子的贡献，以及(Ii)分子轨道能量偏移量epsilon(G)与Fowler-Nordheim最小值电压V-t的线性关系，从而验证了Song等人的门控单分子器件的跃迁电压谱。(C)2012爱思唯尔B.V.保留所有权利。
We show that, if adequately formulated for molecular electronics, the barrier picture can quantitatively reproduce the currents and describe the orbital gating in the molecular transistors fabricated by Song et al. [H. Song, Y. Kim, Y.H. Jang, H. Jeong, MA. Reed, T. Lee, Nature 462 (2009) 1039]. Based on our results, we demonstrate (i) that the measured current represents the contribution of a single molecule, and (ii) the linear dependence of the molecular orbital energy offset epsilon(g) on the voltage V-t at the Fowler-Nordheim minimum, validating thereby the transition voltage spectroscopy for the gated single molecule devices of Song et al.
