Source sentences:
text: For a semiconductor-vacuum interface (that is, the surface of a semiconductor), electron affinity, typically denoted by E EA or χ, is defined as the energy obtained by moving an electron from the vacuum just outside the semiconductor to the bottom of the conduction band just inside the semiconductor:
text: Electron affinity can be defined as either the energy released by adding an electron to a gaseous atom (negative quantity) or the energy required to remove an electron from a gaseous anion (positive quantity).
