"Graphene Ribbons: Nanoscale Heat-to-Power Conversion"

Quantum physicist Mickael Perrin is using graphene nanoribbons to build nanoscale power plants that can convert waste heat from electrical equipment into electricity with minimal loss, aiming to revolutionize the practical application of quantum technologies. His research has garnered prestigious awards and recognition, and he leads a research group at Empa while also serving as an Assistant Professor of Quantum Electronics at ETH Zurich. Perrin's work focuses on combining thermodynamics and quantum mechanics to achieve electricity production with almost zero energy loss, utilizing graphene nanoribbons with unique properties that allow for efficient conversion of thermal energy into electricity even at higher temperatures. However, there are still challenges to overcome before this technology can be practically implemented in devices like smartphones.

"Nanoscale Marvels: Harnessing Carbon-Based Quantum Technology"

Researchers at Empa, in collaboration with international teams, have successfully contacted individual graphene nanoribbons using carbon nanotube electrodes. Graphene nanoribbons, which have unique electrical, magnetic, and optical properties, hold great potential for quantum technology applications. The researchers overcame the challenge of accessing and contacting the extremely narrow nanoribbons by using carbon nanotubes of similar size. The success of this experiment opens up possibilities for studying fundamental quantum effects and developing applications in quantum switching, sensing, and energy conversion. Further research aims to manipulate different quantum states on a single nanoribbon and explore the use of nanoribbons as highly efficient energy converters.
