3 eV. 14. As a result the e-h pair disappear; this process is called recombination. Electron-hole pairs are produced by (a) recombination (b) thermal energy (c) ionization (d) doping 12. Photon absorption Electron-hole pairs are produced by (a) recombination (b) thermal energy (c) ionization (d) doping. This state can be produced by purely electrical means by forward-biasing a pn junction. Both carriers eventually disappear in the process. electron - hole pair recombination When the excited electron meets the hole in the valence band, it may occupy that place. Electron-hole recombination requires an excited semiconductor in which both electrons and holes occupy the same volume of the crystal. The current in a semiconductor is produced by Minimizing electron-hole pair recombination through band-gap engineering in novel ZnO-CeO 2-rGO ternary nanocomposite for photoelectrochemical and photocatalytic applications. > What does combination of holes and electrons make? Recombination of electrons and holes is a process by which both carriers annihilate each other: electrons occupy - through one or multiple steps - the empty state associated with a hole.
