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

Figure 5

The time of energy loss of a hole (solid lines) depending on the final value of the excess energy for anatase (a), rutile (b), and zinc oxide (c). It is assumed that in the initial moment the hole was excited to the level . For comparison, the analogous data are shown (dashed lines) for the energy loss time of excited electrons as calculated based on the results of the works [12, 13].
