Hot Tungsten Clusters: Competition between Atom Ejection and Thermionic Emission
, 1991 This is a first report concerning the thermionic emission of electrons from hot metal clusters. Tungsten clusters were exposed to a 10 ns laser pulse, and the delayed emission of electrons from the clusters was recorded as a function of time after the ...

Enhancement of thermionic emission by light
, 2017 In this paper the rate of electron emission from an illuminated hot metallic plate has been evaluated on the basis of the free electron theory of metals and Fowler’s theory of photoelectric electron emission.

Journal of Applied Polymer Science, Volume 143, Issue 36, September 20, 2026.Thermal black improves polyurethane foam structure and stability. It helps the foam rise smoothly while promoting the formation of smaller, more uniform cells. The foam keeps its strength and insulation performance while reducing shrinkage. Its clean production and easy processing make it a sustainable, cost‐effective option for high‐performance ...

Modifications of Richardson-Dushman Thermionic Emission Current Density Equation for Nano- Materials [PDF]
, 2016 The noble prize winning Richardson-Dushman equation (RDE) had been found to be quite applicable for thermionic emission from metals as far as temperature variation is concerned except the fact that the thermionic emission constant vary from metal to ...

Study shows effect of surface preparations on improving thermionic emission [PDF]
, 1966 Specimen thermionic emitters were electropolished and electroetched to study the effect of surface preparations on improving thermionic emission. The best technique found was to electropolish the annealed rhenium surface and then electroetch it.

Device Simulation of Hole Transport in 233 nm Multiquantum Well AlGaN‐Based UV LED
physica status solidi (a), Volume 223, Issue 17, 9 September 2026.Deep‐UV LEDs suffer from low hole injection efficiency. In this work, electro optical simulations of AlGaN DUV LEDs with 6, 12, and 21 quantum wells, emitting at 233 nm, reveal efficient inter‐well hole transport within the active multiple quantum well region. The data are consistent with experimental findings.

physica status solidi (a), Volume 223, Issue 17, 9 September 2026.Time‐resolved mixed‐mode technology computer aided design simulations reveal that the transient ionization response of deep boron acceptors fundamentally modifies the charge‐sharing mechanism in diamond TMBS rectifiers. Consequently, the optimum trench geometry under dynamic reverse‐bias conditions differs significantly from conventional quasi‐static ...
