1:25 pm:
Condensed Matter Seminar in 210 Physics
Speaker: Hari Manoharan, Stanford University
Subject: Energy Gap Texturing in Complex Two-Dimensional Electronic Systems

In this talk I will show some of our recent work involving spatial patterning of energy band gaps from the nanoscale down to atomic dimensions. Within various two-dimensional materials, these methods can be used to control charge and spins, funnel excitons, and create new lower-dimensional topologically confined states. I’ll present some examples from strain-textured monolayer dichalcogenides, valley-polarized boundary states in molecular graphene, and spin-polarized surface states emerging from a bulk band insulator.
