WebOct 11, 2024 · The electron affinity is the energy change when an atom gains electrons. The convention is that the higher or more positive the electron affinity value, the more readily the atom accepts an electron.
WebMay 24, 2024 · It is well recognized that the electron affinity is hardly affected by doping, which is to shift the Fermi level with little impact on the band gap of a semiconductor. … WebJan 30, 2024 · By doing some careful experiments and calculations, Pauling came up with a slightly more sophisticated equation for the relative electronegativities of two atoms in a molecule: E N ( X) − E N ( Y) = 0.102 Δ. In that equation, the factor 0.102 is simply a conversion factor between kJ and eV to keep the units consistent with bond energies.
