Abstract

Transmission electron microcopy (TEM) in both the parallel illumination and scanning probe mode revealed atomically ordered entities within a 5 to 250 nm range in a IV-VI and a II-VI compound semiconductor quantum dot (QD) system. While the II-VI system was a nominal [001] CdSe/(Mn0.1Zn0.9)Se multilayer structure with the QDs embedded, the IV-VI system nominally consisted of [111] PbSe islands. The comparison of photoluminescence (PL) spectra from the CdSe/(Mn0.1Zn0.9)Se structure with those of a reference structure, that was grown to the same nominal specification under otherwise identical conditions except that no Mn was incorporated into the cladding layers, revealed for the former sample two peaks at approximately 2 and 2.1 eV. We tentatively attribute these two PL peaks to two groups of atomically ordered entities.

20. The Lund University group [16] offers a different qualitative explanation for long range ordered microstructures in a III-V QD system. It is not clear if their samples were analyzed immediately after the growth. At least some of their samples were, however, baked at 120 °C for 12 hours before the analyses. This might have converted growth induced short range order into the observed long range ordered microstructures.Google Scholar

22. The fact that we observe neither (essentially) 2D remains of the nominally deposited 0.3 ML CdSe sheets nor 3D quantum dots with sphalerite structure in our HRTEM and Z-STEM investigations may be explained by averaging effects due to the [001] and <110> projections in the former case and a small density in the latter case.+projections+in+the+former+case+and+a+small+density+in+the+latter+case.>Google Scholar
