A THz-Vibration to THz-Radiation Converter Based on Gold Nanoobjects: a Feasibility Study

Abstract

The estimations done confirm a feasibility of the idea that gold nanobars (GNBs) and nanorings (GNRs) irradiated by microwaves could become the terahertz (THz) emitters with photon energies within the full width at half maximum of longitudinal acoustic phononic DOS of gold (~13.7-17.5 meV, i.e., 3.3-4.2 THz). A scheme of the THz radiation source is suggested based on the domestic microwave oven irradiating a substrate with multiple deposited GNBs or GNRs.
