Single-electron induced surface plasmons on a topological nanoparticle

Single-electron induced surface plasmons on a topological nanoparticle

The surface states in topological insulators are delocalised and immune to imperfections. Here, the authors show that single electrons in topologically protected surface states on a nanoparticle can create a surface charge layer that screens the particle, mediating interaction between bulk phonons a...

description The surface states in topological insulators are delocalised and immune to imperfections. Here, the authors show that single electrons in topologically protected surface states on a nanoparticle can create a surface charge layer that screens the particle, mediating interaction between bulk phonons and light, giving an additional absorption peak.
