Transport Through a Network of Topological Channels in Twisted Bilayer Graphene
Transport Through a Network of Topological Channels in Twisted Bilayer Graphene
We explore a network of electronic quantum valley Hall (QVH) states in the moir\'e crystal of minimally twisted bilayer graphene. In our transport measurements we observe Fabry-P\'erot and Aharanov-Bohm oscillations which are robust in magnetic fields ranging from 0 to 8T, in strong contrast to more conventional 2D systems where …
