Abstract:

The oscillator strength of negatively charged exciton trion in ZnSeZn,MgS,Se quantum-well structures with n-type modulation doping is studied by reflection spectroscopy as a function of electron concentration and temperature. The trion oscillator strength is found to increase linearly with increasing electron concentration up to 6 x 10exp10 cmexp-2. The effect of oscillator strength shearing between the exciton and trion states is observed. The value of the oscillator strength shearing is found to be not more than 20.
