Light-Switchable Graphene Transistors: New Paper in ACS Omega

Check out our new paper in the ACS Omega. In a collaborative study, Piotr Cieciórski, MSc and Dr Wojciech Danowski, alongside with team from the University of Perugia (Italy) and University of Strasbourg (France), constructed a new transistors based on graphene and DTE moleculart switxches.

Optically Responsive Field-Effect Transistors Based on Graphene/Diarylethene Hybrid Films

In this study, we combined graphene with two diarylethene molecular photoswitches that form ultrathin, non-covalently bound layers on its surface. The molecules can be reversibly switched between their open and closed forms using light, allowing the electronic properties of the hybrid graphene interface to be remotely controlled.

By investigating the photoswitching behaviour of the diarylethenes both in solution and on graphene, we established a relationship between their light-induced transformations and changes in the drain current of graphene-based field-effect transistors. The results demonstrate how molecular photoswitches can be used to reversibly tune the operation of electronic devices, providing a modular strategy for developing light-responsive optoelectronic systems.

Congratulations to all authors.
