Exciton lifetime in InAs/GaAs quantum dot molecules
C. Bardot, M. Schwab, M. Bayer +3
The exciton lifetimes in arrays of InAs/GaAs vertically coupled quantum dot pairs have been measured by time-resolved photoluminescence. A considerable reduction of by…

Photoluminescence investigations of 2D hole Landau levels in p-type single Al_{x}Ga_{1-x}As/GaAs heterostructures
M. Kubisa, L. Bryja, K. Ryczko +7
We study the energy structure of two-dimensional holes in p-type single Al_{1-x}Ga_{x}As/GaAs heterojunctions under a perpendicular magnetic field. Photoluminescence measurments wi…
