[Tu-P-68] Tuneable Dot Platform for Controllable Electron Optics in Graphene

〇Fereshteh Ildarabadi Ildarabadi¹, Stephen Power¹ (1. Dublin City University (Ireland))

We propose a Tunable Dot Platform in graphene consisting of arrays of independently gated quantum dots for programmable control of electron scattering. Using differential evolution, optimized dot configurations enable directional current steering, focusing, beam splitting, and valley-selective electron flow.
