Abstract

Owing to the unique properties of evanescent fields, surface waves show great applications in near field enhancement and in breaking the resolution limit. In this work, we found the amorphous-state Bi₂Te₃ film deposited by pulsed laser deposition exhibits surface wave properties in an ultrawide waveband ranging from the visible to near-infrared regions. We analyze the surface wave in three ways: the propagation form, localized form, and coupling with a gold nanobar. This work not only breaks the strict limit of a Bi₂Te₃ topological crystalline insulator but also widens the wavelength region of surface waves compared with a previous report.
