Valley-dependent electron optics using quantum dots in bilayer graphene
Fereshte Ildarabadi, Stephen R. Power
Electrostatically defined quantum dots (QDs) with layer-antisymmetric gating in Bernal-stacked bilayer graphene (BLG) open a local gap and generate a mass-like term with opposite s…

Tunable Dot Platform for Controlling Electron Flow in Graphene
Fereshte Ildarabadi, Stephen R. Power
We introduce an innovative graphene-based architecture to control electronic current flows. The tunable dot platform (TDP) consists of an array of gated dots, with independently ad…

One-dimensional topological channels in heterostrained bilayer graphene
Nina C. Georgoulea, Nuala M. Caffrey, Stephen R. Power
The domain walls between AB- and BA-stacked gapped bilayer graphene have garnered intense interest as they host topologically-protected, valley-polarised transport channels. The in…
