A survey of the most interesting results on nanometer-scale organic thin film transistors (nano-OTFT) is presented. Additionally, we discuss our recent results on the properties of end-group functionalized organic self-assembled monolayers and on their use in the fabrication of nanometer-scale field-effect transistors. Nanometer-scale organic transistors (channel length 30 nm) were fabricated, with a self-assembled monolayer as gate insulator. The carrier transport in these transistors, as a function of the channel length, was investigated, and a transition from a dispersive to a ballistic transport at a channel length of 200 nm was observed. On a molecular scale, alkyl monolayers functionalized at their omega-ends by aromatic moieties were prepared. A high anisotropic conductivity in molecular insulator/semiconductor heterostructures of monolayer thickness was observed. These molecular architectures provide a basis for the building blocks of molecular transistors.
本文介绍了对纳米级有机薄膜晶体管（纳米OTFT）最有趣结果的一项调查。此外，我们还讨论了关于端基功能化有机自组装单分子层的性质及其在纳米级场效应晶体管制造中的应用的近期研究成果。制备了以自组装单分子层作为栅极绝缘体的纳米级有机晶体管（沟道长度为30nm）。研究了这些晶体管中载流子传输与沟道长度的函数关系，并观察到在沟道长度为200nm时从色散传输到弹道传输的转变。在分子尺度上，制备了在其ω端被芳族部分功能化的烷基单分子层。在单层厚度的分子绝缘体/半导体异质结构中观察到了高各向异性导电性。这些分子结构为分子晶体管的构建模块提供了基础。
