有机硅烷自组装单分子膜，嵌入在有机单晶场效应晶体管，显着影响亚阈值特性的转移特性。极化或接近非极化的分子单层沉积在SiO2/掺杂Si衬底上，然后软附着红荧烯薄单晶以形成“叠层晶体”晶体管。由于SiO2表面的有效钝化，该器件已经实现了低至0.11 V/十倍的亚阈值摆幅。它还表明，阈值栅电压被移动的单分子膜的极化，表明器件的阈值是可调的硅烷材料的选择。这两种功能都与逻辑电路元件等低功耗应用密切相关。
Organosilane self-assembled monolayers, embedded in organic single-crystal field-effect transistors, significantly affect subthreshold properties in the transfer characteristics. The monolayer of either polarized or nearly unpolarized molecules is deposited on a SiO 2 /doped Si substrate before softly attaching a rubrene thin single crystal to form the “laminated crystal” transistors. As a result of effective passivation of the SiO2 surface, the device has achieved a subthreshold swing as low as 0.11 V/decade. It is also demonstrated that threshold gate voltage is shifted by polarization of the monolayers, indicating that threshold of the device is adjustable by the choice of silane materials. Both of the functions are closely associated with low-power applications such as logic-circuit components.
