THz-spectroscopic studies on electron dynamics in a GaAs single quantum well and an InAs single quantum dot

Schneider, H.; Schmidt, J.; Stephan, D.; Bhattacharyya, J.; Winnerl, S.; Dimakis, E.; Helm, M.

Intense, spectrally narrow terahertz fields from the free-electron laser (FEL) facility FELBE in Dresden, Germany, provide interesting opportunities for investigating the carrier dynamics in III-V semiconductor nanostructures. This talk will focus on recent FEL studies on dressing intersubband transitions in a wide GaAs single quantum well using terahertz time-domain spectroscopy, and on exciton dynamics in a single InAs/GaAs quantum dot using time-dependent photoluminescence.

Keywords: terahertz free-electron laser; intersubband; exciton; quantum well; quantum dot
