Hole-Phonon Relaxation and Photocatalytic Properties of Titanium Dioxide and Zinc Oxide: First-Principles Approach

Figure 2

The mean characteristics of the hole-phonon (empty rhombus) and electron-phonon (black rhombus) relaxation for anatase as functions of the excess energy . Here is the constant of interaction, is the rate of energy loss according to (7) and (11), and is the mean energy lost with emission of one phonon, in accordance with (9), (12), and (13).
