Molecular transistors: from strings and rings to other things

点击翻译按钮获取中文摘要

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.
