As a noncontact strategy with flexible tools and high efficiency, laser precision engineering
is a significant advanced processing way for high-quality micro-/nanostructure fabrication …

Thermal and concentrated solar solid-state converters are devices with no moving parts,
corresponding to long lifetimes, limited necessity of maintenance, and scalability. Among the …

With the aim of presenting the processes governing the Laser-Induced Periodic Surface
Structures (LIPSS), its main theoretical models have been reported. More emphasis is given …

A material with a low work function exhibiting field-emission of electrons has long been
sought as an ideal point electron source to generate a coherent electron beam with high …

Thermionic-photovoltaic (TIPV) converters exploit both electrons and photons emitted by a
hot cathode to produce electric power. In this work, a TIPV converter structured with a …

Despite its great potential, thermionics has a low Carnot efficiency because a considerable
percentage of cathode thermionic energy is wasted to heat the anode. This paper introduces …

Low work function materials are attracting researchers worldwide as potential thermionic
emitters or collectors. In this study, a number of composite cathodes using a promising …

Abstract Lanthanum hexaboride (LaB 6) single-crystals are known from a long time for their
excellent thermionic and field-assisted electron-emitting properties. Recently, multi …

Polycrystalline lanthanum hexaboride (LaB 6) discs were sintered by hot pressing of
commercial powders and successively polished, in order to investigate their thermionic …

Thin films based on aluminum nitride were obtained by fs-laser assisted Pulsed Laser
Deposition (fs-PLD) at room temperature on tantalum substrates for studying the electron …
