Photoemission of Plasmonic Gold Nanostars in Laser-Controlled Electron Current Devices for Technical and Biomedical Applications

open access: yesSensors, 2022
The main goal of this work was to modify the previously developed blade-type planar structure using plasmonic gold nanostars in order to stimulate photofield emission and provide efficient laser control of the electron current.

Reconsideration of Temperature Determined by the Excited-State Population Distribution of Hydrogen Atoms Based on Tsallis Entropy and Its Statistics in Hydrogen Plasma in Non-Equilibrium State

open access: yesEntropy, 2023
In non-equilibrium plasmas, the temperature cannot be uniquely determined unless the energy-distribution function is approximated as a Maxwell–Boltzmann distribution.

Room-temperature single-electron junction. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1996
The design, realization, and test performances of an electronic junction based on single-electron phenomena that works in the air at room temperature are hereby reported. The element consists of an electrochemically etched sharp tungsten stylus over whose tip a nanometer-size crystal was synthesized.

ECE imaging of electron temperature and electron temperature fluctuations (invited)

open access: yesReview of Scientific Instruments, 2001
Electron cyclotron emission imaging (ECE imaging or ECEI) is a novel plasma diagnostic technique for the study of electron temperature profiles and fluctuations in magnetic fusion plasma devices. Instead of a single receiver located in the tokamak midplane as in conventional ECE radiometers, ECEI systems utilize large diameter imaging optics coupled ...

Generation mechanism of precursor electrons ahead of a hypersonic shock wave in argon

open access: yesJournal of Fluid Science and Technology, 2014
The purpose of the research is to clarify the generation mechanism of precursor electrons ahead of a hypersonic shock wave in argon. The triple-probe measurements and radiation measurements are carried out using a hypersonic shock tube.

Comparison between electropositive and electronegative cold atmospheric-pressure plasmas: a modelling study

open access: yesHigh Voltage, 2016
Cold atmospheric-pressure He + N(2) and He + O(2) plasmas are chosen as the representatives for electropositive and electronegative plasmas, of which the discharge characteristics are studied and then compared to each other by fluid models.

Electron Temperature Observed with the Langmuir Probe and Electron Temperature Probe

open access: yesJournal of geomagnetism and geoelectricity, 1971
Intercomparison between the Langmuir probe and the electron temperature probe which has been developed by the authors, in the measuring of the electron temperature, was carried out two times by using two rockets, K-9M-28 and K-9M-29.The difference between the results obtained with two probes will be discussed and the inconsistency between the electron ...
