| dc.description.abstractEn | An accurate determination of the effective trap density in CdTe:V is performed using both counterpropagating (small grating spacing) and copropagating (large grating spacing) two wave mixing. This enhanced precision allows to show a variation of the effective trap density with wavelength. We show that such a change is explained when two traps both coupled to the conduction and the valence bands are present. New theoretical expressions for the electron hole competition coefficient and Debye screening length are derived and used | |
