The development of ultrathin dielectrics for low power electronics operations, flexible and printed electronics, and field‐effect‐transistor‐based sensors is still a challenge. Here, monolayers of engineered lipids supported on silicon are reported presenting exceptional mechanical and dielectric properties. The lipid monolayers are stabilized using a simple procedure based on a two‐stage reticulation process in both their aliphatic chains and their head‐group. With a thickness lower than 3 nm, such layers are demonstrated to offer exceptional mechanical and dielectric stability with unprecedented low leakage current and dielectric strength. Surprisingly, the mechanical and dielectric pressures required to rupture/breakdown the monolayers are shown to be similar. These results suggest the presence of a strong correlation between mechanical and dielectric properties, as well as between the mechanisms of rupture and breakdown.

具有前所未有的机械和介电性能的超薄型脂质单分子膜

用于低功率电子设备操作，柔性和印刷电子设备以及基于场效应晶体管的传感器的超薄电介质的开发仍然是一个挑战。在此，据报道，载于硅上的工程脂质单层具有出色的机械和介电性能。使用基于两步网状化过程的简单程序，在脂族链和头基团中稳定脂质单分子层。这种层的厚度小于3 nm，具有出色的机械和介电稳定性，并具有前所未有的低泄漏电流和介电强度。令人惊讶地，显示出使单层破裂/破裂所需的机械和介电压力是相似的。
