Abstract
Structures and methods are provided for shielding field emitter devices from radiation. In an embodiment, a shielding layer inhibits radiation from degrading field emitter devices while exerting a predetermined force upon the field emitter devices so as to restrain from damaging the structure or affecting performance of the devices. In an embodiment, the field emitter under the protection of the shielding layer sustains structural equilibrium. In an embodiment, the field emitter sustains structural elasticity. In an embodiment, the shielding layer is comprised of tetratantalum boride, which inhibits radiation from degrading field emitter devices while exerting a predetermined force upon the field emitter devices so as to restrain from damaging the structure or affecting performance of the devices. In other embodiments, the field emitter under the protection of the tetratantalum boride layer sustains structural equilibrium or structural elasticity.
