Dependence of the energy levels and PL spectra of AQDP #1. (a) Dependence of the energy levels on the magnetic field (the first (second) number in the label indicates the branch (polarization)). (b) PL spectrum of an AQDP consisting of a bottom dot with diameter (height) DB=12 nm (hB=2.4 nm) and top dot with diameter (height) DT=24 nm (hT=1.8 nm) at 5 K. (c) As in (b) but at 70 K. The red (blue) line corresponds to polarization -1 (+1) in z.
