研究目的
To determine all the period of nanostructure subwavelength that can be observed during irradiation by multipulse femtosecond laser in dielectric materials, specifically Sapphire, using a generalized plasmonic model.
研究成果
The generalized plasmonic model has been demonstrated to be efficient in following the evolution of periodic nanostructures of HSFL type in dielectric material such as Sapphire, at wavelengths between 300 nm and 1400 nm. The results show that the period of the nanostructures and the depth of the pseudo-metal layer increase with the increase of the femtosecond laser wavelength, enhancing the surface absorption of Sapphire, which is suitable for applications in micro-solar cells devices.
研究不足
The study is limited to the use of a generalized plasmonic model and does not include experimental validation of the nanostructures periods calculated.
