Electron affinity (electron gain elthalpy) increases with increase of nucleat charge but decreases with increases of atomic size.
The main cause of this effect is the jump in the electron g -factor at the semiconductor-vacuum interface (from g * = 0.44 in GaAs to g 0 = 2 in vacuum). Owing to the jump in the electron g -factor, the effective electron affinity depends on the mutual orientation of optically ...

The electron affinity (EA) χ of single crystal diamond (100) is determined as a function of hydrogen and oxygen coverage by a combination of work function... F Maier,J Ristein,L Ley - 《Physical Review B》 被引量: 293发表: 2001年 The role of atomic hydrogen and its influence on the...
The high electron affinity of γ-graphyne and its promising electron transport properties suggest that the material can be involved into PET and be used in organic photovoltaics. To better understand this issue, we considered several vdW complexes formed by γG5 and typical electron donor and elect...
19 In the Mulliken definition, electronegativity is based on the average of the ionization potential (Ip) and electron affinity (EA) for an atom. Hinze and Jaffeé extended the Mulliken definition to valence states by using Ip and EA data taken from electronic spectroscopic data for atomic ...
(a) Ionization energy (b) Electron affinity What does it mean when we say that electrons are paired? If the H-atom electron in the n = 1 state absorbs energy equivalent to 2.178 times 10^{-18} J, what energy state will it occupy? Provide the orbital diagram for the excited state ...
3(b)), thereby reflecting a systematic dependence on the surface electron affinity modified by surface band-bending due to hydrogen atom surface termination and Fermi level pinning. Above a critical Vdef, energy-filtering has practically little impact on doping contrast (Fig. 3(c)) as surface ...
