Far-field femtosecond laser-driven λ/73 super-resolution fabrication of 2D van der Waals NbOI2 nanostructures in ambient air

Fabrication and characterization of nano-groove array structures

We confirmed the feasibility of fabricating super-resolution NGA structures on 2D NbOI₂ using fs laser irradiation. The 2D multilayer NbOI₂ nanosheets were mechanically exfoliated…
