The curvature-corrected field emission current density, obtained by linearizing at or below the Fermi energy, is investigated. Two special cases, corresponding to the peak of the normal energy distribution and the mean normal energy, are considered.

The dependence of the notional emission area on the apex electric field for a single field-emitter tip is investigated for cylindrical posts. It is found that a power-law dependence on the local field exists only when the end-cap on the cylinder is m

Field emission tips with apex radius of curvature below 100nm are not adequately described by the standard theoretical models based on the Fowler-Nordheim and Murphy-Good formalisms. This is due to the breakdown of the `constant electric field' assum

A simple expression for the Gamow factor is obtained using a second order curvature corrected tunneling potential. Our results show that it approximates accurately the `exact-WKB' transmission coefficient obtained by numerically integrating over the

In the quasi-planar approximation of field emission, the potential energy due to an external electrostatic field $E_0$ is expressed as $-e \gamma E_0 \Delta s$ where $\Delta s$ is the perpendicular distance from the emission site and $\gamma$ is the

The curvature of field emitter tips leads to an altered tunneling potential that assumes significance when the radius of curvature is small. We provide here an analytical curvature-corrected formula for the field emission current from smooth vertical

The image-charge potential plays a key role in field emission by lowering the potential barrier, thereby leading to an increase in current density by orders of magnitude. The classical image-charge potential is however strictly applicable to planar e
