  • Dielectric strength - Wikipedia

    Dielectric films tend to exhibit greater dielectric strength than thicker samples of the same material. For instance, the dielectric strength of silicon dioxide films of thickness around 1 μm is about 0.5 GV/m. However very thin layers (below, say, 100 nm) become partially conductive because of electron tunneling.
