For the bipolaron , the sum of the threshold energies of the two transitions should
equal the energy of the band gap : ho , + ħuz = Eg In addition to the number of
optical transitions and their position in energy , it is important to know the

In addition , the absorption at 0 . 45 eV is accompanied by an increase of the
absorption at 1 . 4 eV with relative change of about 0 . 1 and by bleaching in the
intrinsic absorption region [ 4 . 97 ] . Measurements of the IR modes after a delay
of ...
