Hyperbolic enhancement of photocurrent patterns in minimally twisted bilayer graphene

Hyperbolic enhancement of photocurrent patterns in minimally twisted bilayer graphene

Here, the authors use scanning probe photocurrent imaging to resolve nanoscale variations of the Seebeck coefficient occurring at domain walls separating micron-scale AB and BA stacking regions in twisted bilayer graphene, and observe hyperbolic enhancement of the photocurrent pattern.
