Magneto-photoluminescence of heavy- and light-hole excitons in site-controlled pyramidal quantum dots
2008 (English)In: Physica. E, Low-Dimensional systems and nanostructures, ISSN 1386-9477, Vol. 40, no 6, 1873-1875 p.Article in journal (Refereed) Published
Pyramidal, site-controlled InGaAs/AlGaAs quantum dots (QDs) are studied by micro-photoluminescence (PL) spectroscopy in a magnetic field. The light-hole (LH) excitonic transitions exhibit diamagnetic shifts similar to those of their heavy-hole (HH) counterparts. From the evolution of the excitonic lines, effective g-factors of g=1.7 and 0.4 for HH and LH neutral excitons are inferred
