Figure 3From: Paradox of low field enhancement factor for field emission nanodiodes in relation to quantum screening effectsField emission properties and FN plot. Properties of (a) the current density versus applied field and (b) the corresponding FN plot for a single P-SiNT nanodiode (red circle), P-SiNT array nanodiode (hollow circle), and P-SiNT array microdiode (hollow square).Back to article page
