研究目的
Investigating the conditions for the generation of slow surface plasmon waves in arrays of single-walled carbon nanotubes under continuous laser radiation to enhance the efficiency of converting laser radiation into terahertz radiation.
研究成果
The study demonstrates that laser-irradiated CNTs can efficiently generate THz and far-IR radiation, with frequency control achievable by adjusting the laser incidence angle. This approach offers a promising avenue for developing compact THz radiation sources operating at room temperature.
研究不足
The study is theoretical and numerical, lacking experimental validation. The practical implementation of ordered CNT arrays and precise control of laser incidence angles may pose technical challenges.
