An optical indirect transition can be assisted by more than one phonon. Therefore, how to determine the indirect energy gap and that of each phonon.

13 March 2013 1 7K Report

In the case of an indirect transition assisted by two or more phonon, how can I determine Egi (indirect gap) and energy Eph of each phonon .

Yuriy P. Gnatenko

In order to determine zero-phonon indirect transition of semiconductor material it is necessary to carry out the temperature dependence of the absorption edge analogously as we made in the following paper for GaSe crystals.
