Efficient infrared thermal emitters based on low-albedo polaritonic meta-surfaces

A low-albedo all-semiconductor meta-surface with spectrally selective absorption peaks is demonstrated. By engineering the dimensions and shapes of the semiconductor antennas comprising the meta-surface, simultaneous reduction of reflectivity and enhancement of absorption are accomplished by control...

Zusammenfassung:A low-albedo all-semiconductor meta-surface with spectrally selective absorption peaks is demonstrated. By engineering the dimensions and shapes of the semiconductor antennas comprising the meta-surface, simultaneous reduction of reflectivity and enhancement of absorption are accomplished by controlling their electric and magnetic resonances. Thermal emissivity of the silicon carbide-based meta-surface is experimentally measured and found in agreement with both absorption measurements and theoretical predictions.
