There is a growing trend to apply field emission (FE) electron sources in vacuum electronic
devices due to their fast response, high efficiency and low energy consumption compared to …

Electron field emission is a quantum tunneling phenomenon whereby electrons are emitted
from a solid surface due to a strong electric field. Graphene and its derivatives are expected …

The density functional theory (DFT) levels B3LYP, B3PW91 and CAM-B3LYP/6–31+ G (d)
were used to systematically evaluate the reactivity, electronic, linear and non-linear optical …

We fabricate AlGaN nanowires by molecular beam epitaxy and we investigate their field
emission properties by means of an experimental setup using nano-manipulated tungsten …

The carbon nanotube (CNT) cold cathode can provide a high current and current density for
microwave devices, which normally work under pulse mode. In this work, we studied the …

Large scale, uniform single-layer graphene was transferred onto well-aligned ZnO nanowire
arrays to produce high density nanoscale protrusions within graphene for efficient field …

Graphenated multi-wall carbon nanotube (g-MWCNTs) were obtained by means of plasma
enhanced chemical vapor deposition (PECVD). The effect of C 2 H 2/H 2 gas ratio was …

Silicon nanorods (SiNRs) with a large interspace and regularly aligned structure were
fabricated by combining silver-catalyzed etching with a polysterene (PS) sphere template …

Experimental current-voltage characteristics (IVCs) of carbon nanotube (CNT)-based large-
area field emitters (LAFEs) were measured and analyzed using a “two-class model”, in …

A novel chemical ionization (CI) source has been developed based on a carbon nanotube
(CNT) field emission electron source. The CNT-based electron source was evaluated and …
