Educational Java applets get in power electronics labs
This paper presents Java applet programs for a WWW (world wide web)-HTML (hypertext markup language)-based multimedia course in basic power electronics circuits. These tools make use of the benefits of Java language to ...
Absence of Cooper-type bound states in three- and few-electron systems
It is shown that the appearance of a fixed-point singularity in the kernel of the two-electron Cooper problem is responsible for the formation of the Cooper pair for an arbitrarily weak attractive interaction between two ...
Mylar Secondary Emission-energy Distribution and Yields
(Institute of Electrical and Electronics Engineers (IEEE), 2014-02-01)
We have characterized Mylar by determining the emission yield and energy spectrum of emitted secondary electrons. In this study we used a conventional electron accelerator apparatus to which we have made some important ...
Direct profiling of polarization fields in nitride semiconductors at nanometric scale using electron holography in the transmission electron microscope

Energy Distribution of Secondary Electrons from Gold on Teflon-FEP
(Ieee-inst Electrical Electronics Engineers Inc, 2016-10-01)
This paper presents results of the spectrum of energy of secondary electrons for the energies of perpendicularly incident electrons of 0.4 keV, 2.0 keV, or 3.5 keV in a gold surface deposited on a substratum of Teflon-FEP. ...
On the location of the electron lone pair of XeF6 and related molecules
Theoretical results based on the use of the electron localization function confirmed, for the first time, the predictions of the valence shell electron pair repulsion model about the electron lone pair on the XeF6 and ...
Using shifts in the electronic emission curve to evaluate polymer surface degradation
(Elsevier B.V., 2001-01-01)
The polymer surface degradation and/or modification evolution of Teflon FEP and Mylar C films caused by a low energy electron beam were analyzed using a new method that consists in measuring the second crossover energy ...
Pairing and unpairing electron densities in organic systems: Two-electron three center through space and through bonds interactions
(American Institute of Physics, 2014-05)
Two-electron three-center bonding interactions in organic ions like methonium (CH + 5 ), ethonium (C2H + 7 ), and protonated alkanes n−C4H + 11 isomers (butonium cations) are described and characterized within ...
