François Lapointe


Roles and responsibilities

Research Associate — Security and Disruptive Technologies Research Centre — Developing and optimizing materials for novel electronic devices.

Current research and/or projects

Carbon nanotubes present exceptional optical and electrical properties and they can be processed as an ink for printed electronics. Dr Lapointe implements a highly purified semiconducting carbon nanotube material into functional electronic devices for logics, gas sensing, and artificial intelligence.

Research and/or project statements

  • Understanding and optimizing the characteristics of carbon nanotube electronic devices through their electrostatics and doping state.
  • Developing novel strategies for gas sensing with carbon nanotube electronic devices.
  • Enabling better stability and reproducibility in carbon nanotube devices through understanding of the interactions with the ambient.
  • Designing and characterizing novel carbon nanotube device architectures for hardware-based artificial intelligence.
