Abstract
The polarization anisotropy (PA) of the 1e-1hh optical transitions in [100]-quantum wells (QWs) A2B6 with semimagnetic barriers A 21−x Mn x B6 in a magnetic field applied in the QW plane is studied. This anisotropy stems from the mixing of light- and heavy-hole (HH) states by interactions, which reduces the in-plane symmetry of structure. Zeeman energy of carriers in a magnetic field G, which is exchange-enhanced due to presence of the semimagnetic barrier, as well as in-plane strains and effects of an interface asymmetry are taken into account. Comparison of ∝ (J x J y + J y J x) and ∝ (J 3 x G y + J 3 y G x C2v-invariants manifestations in the luminescence PA in the presence of in-plane magnetic field is reported (here J is a hole angular moment).
We predict and analyze a new effect of PA singularity caused by interference of HH splitting due to Zeeman energy in third order ∝ G 3 and linear on G contribution mediated by C2v interaction. The quantitative evaluation of 1e-1hh luminescence PA is carried out in terms of electron and hole spin temperatures. It is shown that fluctuations of potential due to QW interface roughness can result in redistribution of π-periodic and π/2-periodic contributions to the PA. Theoretical analysis compares with our experiments carried out on QW Cd1-xMnxTe/CdTe/Cd1-xMnxTe as well as with the data of other papers.
