Spin polarization in GaAs quantum dots has been investigated in the article [1] featured as Editor's Choice of the present issue. Electrons are polarized through relaxation processes after photoluminescence excitation and are identified by the Hanle effect. The cover figure is a schematic diagram describing the selective removal of negatively polarized excitons by optically pumped spin down electrons, which increases exciton and decreases trion PL polarization, respectively. The corresponding author, Allan Bracker, is a member of NRL's Nanostructures Section, focusing on the physics and application of electronic structures with reduced dimensionality. This paper is an invited presentation from the 2nd International Conference on Semiconductor Quantum Dots held in Tokyo, 30 September–3 October 2002. The full proceedings of this meeting, guest‐edited by Y. Arakawa and S. Tarucha, are published in physica status solidi (c) 0 , No. 4 (2003).
