Electron volt is defined as the energy acquired by an electron when it is accelerated through a potential difference of 1 volt. The value of electron volt (eV) is given as, 1 eV = (1.602 × 10-19 coulomb) × (1 volt) 1 eV = 1.602 × 10-19 joule ...
Electrons are unique from the other particles in multiple ways. They exist outside of the nucleus, are significantly smaller in mass and exhibit both wave-like and particle-like characteristics. An electron is also anelementary particle, which means that it is not made up of smaller components....

What is the difference between electric current and electron flow? Why are they in different directions? There is still a lot of confusion on this issue. It comes from when Benjamin Franklin first discovered electricity he thought it was positive charges that was moving along the wire. So the...

Electric fields provide us with the pushing force we need to induce current flow. An electric field in a circuit is like an electron pump: a large source of negative charges that can propel electrons, which will flow through the circuit towards the positive lump of charges. ...
In other words, the bandgap is the energy required for an electron to transition from the valence band to the conduction band. Si has a bandgap of 1.12eV, SiC a bandgap of 3.26eV, and GaN a bandgap of 3.5eV. The unit for bandgap is eV (electron volt), which is defined as ‘the ...
An ampere is a unit of measure of the rate of electron flow orcurrentin an electrical conductor. One ampere of current represents one coulomb ofelectrical charge(6.24 x 10charge carriers) moving past a specific point in one second. Physicists consider current to flow from relatively positive poi...
In 2014, physicists thought they'd detected a 3.5 kiloelectron volt signal (keV) coming from deep within the Milky Way. This signal was believed to be consistent with what would arise from decaying sterile neutrino dark matter. In 2020, equipped with new data from the XMM-Newton space X-...
