Electron-Volt
An electron-volt (eV) is a unit of energy equal to the amount of kinetic energy gained or lost by an electron when it is accelerated through an electric potential difference of one volt.
History/Origin
The electron-volt was introduced in the early 20th century as a convenient unit for expressing atomic and subatomic energies, especially in quantum physics and particle physics, replacing larger units like the joule for small-scale energies.
Current Use
The electron-volt is widely used in physics and chemistry to quantify energies at the atomic and subatomic levels, such as in spectroscopy, particle physics, and quantum mechanics, due to its convenience in expressing small energy values.
Nanojoule
A nanojoule (nJ) is a unit of energy equal to one billionth (10^-9) of a joule.
History/Origin
The nanojoule was introduced as part of the SI unit system to measure very small amounts of energy, especially in scientific and technological contexts, with its usage becoming more common with advancements in nanotechnology and micro-scale energy measurements.
Current Use
Nanojoules are used in fields such as electronics, nanotechnology, and physics to quantify small energy quantities, including in the measurement of energy consumption in micro- and nano-scale devices.
