Energy gap law electron transfer

WebA band gap is the distance between the valence band of electrons and the conduction band. Essentially, the band gap represents the minimum energy that is required to excite an electron up to a state in the conduction band where it can participate in conduction. [1] The lower energy level is the valence band, and thus if a gap exists between ... WebMay 5, 1991 · The electron-transfer rate as a function of the free energy gap (energy-gap law) was formulated by including the solvent nonlinear response effect and averaging over the distribution of donor-acceptor distances.

WebThe first thing which you have to keep in mind that 'Electron Transfer' only happens with metals. In insulators and semiconductors, the scenario which takes place is called 'Electron Localisation'. The electrons which are transferred or localised are called 'Valence Electrons' which means the electrons residing on the last orbit in an atom.
