Gate-tunable regular and chaotic electron dynamics in ballistic bilayer graphene cavities Open
The dispersion of any given material is crucial for its charge carriers' dynamics. For all-electronic, gate-defined cavities in gapped bilayer graphene, we developed a trajectory-tracing algorithm aware of the material's electronic propert…
