Distinctive Features of Mesa‐Type Metal/Dielectric Surface Grating Structures Assisting Resonant Enhancement of Thermal Emission at Longitudinal–Optical Phonon Energy

Previously, a longitudinal optical (LO) phonon resonant emission (LORE) at 8.5 THz from Au‐GaAs surface microstructures at 630 K is reported. This emission ascribed to thermally generated electric dipoles by the coherently vibrating charges at Au/GaAs/Au interfaces shows no dependence of the emissio...
