| 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. |
