This paper characterizes the rates of charge transport by tunneling across a series of molecules—arrayed in self-assembled monolayers—containing a common head group and body (HS(CH)CONH(CH)-) and structurally varied tail groups (-R). These molecules are assembled in junctions of the structure Ag/SAM//GaO/EGaIn. Over a range of common aliphatic, aromatic, and heteroaromatic organic tail groups, changing the structure of R does not significantly influence the rate of tunneling.
本文描述了一系列分子中隧穿电荷传输的速率,这些分子通过自组装单分子层排列,包含一个共同的头基和主体(HS(CH)CONH(CH)-)和结构上不同的尾基(-R)。这些分子组装在结构为 Ag/SAM//GaO/EGaIn 的结中。在一系列常见的脂肪族、芳香族和杂环芳香族有机尾基中,改变 R 的结构不会显著影响隧穿速率。
