研究目的

To study enhanced optical absorption of plasmonic nanostructures and analyze thermal effects induced by optical absorption and heat transfer between nanostructures.

研究成果

Resonant plasmonic structures allow for control of fundamental optical processes such as absorption and emission. By structuring metal surfaces on the subwavelength scale, plasmonic resonances can be designed to produce high-optical absorption in the broadband of wavelength. The absorbed optical energy is converted to heat, which can lead to significant local heating in metallic nanostructures and induce temperature gradient in the surrounding medium. The heat transfer between nanostructures is significantly enhanced by near field interaction. The thermal effects of plasmonic nanostructures can be used for energy conversion, optical trapping and thermal management.

研究不足

The study focuses on metallic nanostructures and their plasmonic resonance effects. The temperature-dependent data for plasmonic materials is still largely missing, requiring further experiments and analytical models for accurate modeling of high-temperature plasmonic devices.
