Electron-stimulated desorption kinetics of ultra-thin LiCl films on graphene

paqui 8 enero, 2024 30 abril, 20242D materials, Graphene, LiCl films

Although ultra-thin alkali halide films are widely employed substrates due to their insulating behavior, their structural stability upon electron and photon beam exposure is not fully understood. In this study, we focus on the evolution of the LiCl thin film structure on graphene through low-energy electron irradiation. We observe desorption…

Development of a Graphene SG-FET aptasensor able to detect attomolar concentrations of hepatitis C virus core protein

Biosensors based on graphene field-effect transistors have become a promising tool for detecting a broad range of analytes. However, they lack the stability and reproducibility required to step into biotechnological and biomedical applications. ESISNA group has used a promising physical graphene functionalization protocol which allows atomically-precise highly-controlled covalent functionalization, preserving…
