Scalable fabrication of graphene nanoribbon quantum dot devices with stable orbital-level spacing

Scalable fabrication of graphene nanoribbon quantum dot devices with stable orbital-level spacing

Graphene nanoribbons can be used as quantum dot devices, but scalable fabrication methods are needed. Here, a nanobar technique is used to synthesize graphene nanoribbon-based quantum dot devices with a 56 % yield and stable orbital level splitting up to 20 K.
