- ... This work is driven by the vision of engineering planar field emitters with ferromagnetic metal–insulator nanocomposite thin films, using swift heavy ion (SHI) irradiation method. FeCo nanoparticles inside SiO₂ matrix, when subjected to SHI get elongated. Using this, we demonstrate here a planar field emitter with maximum current density of 550 μA/cm² at an applied field of 15 V/μm. The film, irra ...
