Molecular transistors: from strings and rings to other things

该项目旨在利用化学方法开发分子晶体管，这是未来分子电子技术的关键组件。分子作为超小型电子元件的使用正引起工业界和学术界的关注，作为一种解决自上而下的缩放极限的方法。然而，目前基于化学反应或氧化还原状态变化的门控的分子设计是缓慢和低效的。该项目将基于交叉共轭或环状分子的量子干涉特征的能量门控，开发具有极高增益和快速响应的分子晶体管。这将为分子器件的纳米制造提供包括新策略在内的重大好处。

This project aims to use chemical approaches to develop molecular transistors, which are critical components for a future molecular electronics technology. The use of molecules as ultra-miniaturised electronic components is gathering attention from industry and academia, as a solution to the approaching limits of top-down scaling. However, current molecular designs based on gating through chemical reaction or redox state changes are slow and inefficient. The project will develop molecular transistors with exceptionally high gain and fast response based on gating the energy of quantum interference features in molecules with cross-conjugated or ring-like shapes. This will provide significant benefits including new strategies for nanofabrication of molecular devices.
