Electron holography is a useful technique to directly visualize the electromagnetic fields in
and around various functional materials at the nanometer scale. The precision and …

Multi-scale and multi-physics simulations are carried out for nano-emitters consisting of FCC
(Al, Cu and Au), BCC (V, Mo and W) and HCP (Ti, Zn and Zr) metals, using hybrid …

The apex-field enhancement factor (aFEF) is regarded as a meaningful parameter to
characterize field electron emission (FE) devices. If experimentally extracted from orthodox …

A new in situ synthesis method for the growth of MoO2 nanowires via controlled thermal
oxidation of MoS2 flakes is presented, going from a 2D transition metal chalcogenide to a …

One of the critical aspects in advancing high-brightness field emitter devices is determining
the conditions under which single-tip emitters should be constructed to optimize their …

Electrostatic depolarization in clusters of emitters regularly spaced and with uniform height
causes the emission to concentrate on the outer corners, suppressing the relative emission …

Experiments on field electron emission (FE) of single carbon nanotubes (CNTs) indicate that
they exhibit a nearly linear Fowler–Nordheim plot, and the field enhancement factor (FEF) …

The operation of nanoscale electronic devices is related intimately to the three-dimensional
(3D) charge density distributions within them. Here, we demonstrate the quantitative 3D …

Depolarization, also called shielding or screening, is a key phenomenon that can reveal the
conditions under which a macroscopic emitted current density is optimized in large-area …

The electrostatic potential distribution in a 2D diode system with a blade-shaped field emitter
on a flat substrate has been calculated. The anode of the system represents a plane that is …
