“Blurring the boundaries between topological and non-topological phenomena in dots”

Topological insulators (TIs) are known to have unique characteristics that distinguish them from the rest of the other materials, named trivial insulators. More specifically, TIs are a new matter state that behave as an insulator in bulk and a metal in the edges (or surfaces). However, different from the usual metals, the TIs conduct electric current on the edge (or surfaces) without dissipation, thus yielding interesting technological applications. [Read More…]
