Graphene nanoribbon explored as basis for gamma monitoring in fusion machines
A tiny ribbon may hold big promise for detecting radiation damage in future tokamaks.
Researchers at the University of Arizona have shown that, when exposed to gamma radiation, graphene nanoribbons exhibit altered current flow from quantum effects while maintaining their atomic framework, suggesting strong potential for use in sensors for monitoring gamma-induced damage to materials and devices in extreme environments, such as fusion machines.
