Topological insulators are electron are superhighways on their edges and insulators everywhere else. Researchers used a process called high harmonic generation to separately probe electron behavior in both of those domains.

First glimpse of polarons forming in a promising next-gen energy material
Polarons affect a material’s behavior, and may even be the reason that solar cells made with lead hybrid perovskites achieve extraordinarily high efficiencies in the lab. Now scientists have directly seen and measured their formation for the first time.
