Neutral and charged excitons in a CdTe-based quantum well
We present a summary of our spectroscopic studies of the oscillator strength of transitions related to the formation of neutral and positively charged excitons in modulation p-doped CdTe-based quantum wells. The hole concentration was controlled in the range from 10¹⁰ cm⁻² to 10¹¹ cm⁻². Continuou...

| description |
We present a summary of our spectroscopic studies of the oscillator strength of transitions related
to the formation of neutral and positively charged excitons in modulation p-doped
CdTe-based quantum wells. The hole concentration was controlled in the range from 10¹⁰ cm⁻² to
10¹¹ cm⁻². Continuous-wave and time-resolved femtosecond pump–probe absorption measurements
were performed. They allowed us to study the interacting system of excitons, trions, and free
holes. Characteristic times of the system were determined, such as the trion formation time. A new
explanation of so-called oscillator strength «stealing» has been proposed, in terms of spin-dependent
screening. Experimental evidence is presented for optical creation of transient spin polarization
in the quantum well. |
