High-Performance Monolayer Field-Effect Transistors with Aqueous Stability and High Sensitivity

Low-voltage, low-cost, high-performance monolayer field-effect transistors that comprise a densely-packed, long-range ordered monolayer, spin-coated from core-cladding liquid-crystalline pentathiophenes, and a solution-processed high-k HfO2-based nanoscale gate dielectric have been developed. These monolayers are light-sensitive and are able to function as reporters to convert analyte binding events into electrical signals with ultrahigh sensitivity (ca. 10 ppb).

Research Fields

One remarkable aspect in Chemistry is its powerful ability to create new materials; one remarkable aspect in Physics is its powerful ability to investigate the intrinsic properties of these materials, the combination of both enables us to reveal the details of nature and change nature. The research in our molecular materials and devices lab is focused on exploring the optoelectronic properties of novel functional molecular materials and/or low dimensional nanomaterials at the nanometer or molecular level, such as electron transport properties, optoelectronic properties and stimuli-responsive abilities. These materials include single organic molecules/molecular clusters, carbon nanotubes, organic/inorganic nanowires, graphene, biomacromolecules, nanoparticles, and so on. These are challenging and predictable but active and interdisciplinary frontier research areas with many opportunities and great potential applications. Graduate and postdoctoral students working on these projects will have been extensively well-trained in all aspects, including organic syntheses, assembly techniques, micro/nanofabrications, and detection systems. Specifically, our research focuses are listed below:

1. Nano/molecular electronics;

2. Single-molecule dynamics and detection;

3. Organic/flexible electronics;

4. Chemo/biosensors
