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. |
