About eV

1 eV = energy of 1 electron through 1V
Common in semiconductor physics

FAQs

For one electron: eV = V. For n electrons: eV = V × n. Example: 5V with 1 electron = 5 eV.

eV is used in particle physics, semiconductor band gaps, X-ray energies, and atomic/molecular physics where joules would be inconveniently small numbers.
