Abstract

A rigorous analytical study of the eigenmodes supported by a charge accumulation layer within a transparent conductive oxide (TCO) is presented. The new class of surface plasmons termed accumulation-layer surface plasmons (ASPs) is introduced. Near resonance ASPs are tightly bound and display a vast effective index tunability that could be of great practical interest. The suppression of ASPs in the presence of epsilon-near zero regions is discussed.
