Hartree Energy
The Hartree energy (Eh) is a unit of energy used in atomic physics, representing the total energy of an electron in a hydrogen atom in its ground state.
History/Origin
Named after the American physicist Douglas Hartree, the Hartree energy was introduced in the early 20th century as a fundamental atomic unit of energy within the system of atomic units, facilitating calculations in quantum mechanics.
Current Use
The Hartree energy is primarily used in theoretical and computational chemistry and physics to express energies at the atomic and molecular scale, especially in quantum chemistry calculations and atomic physics research.
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.
