Journal ArticleDOI
Investigations on the Stranski–Krastanow growth of CdSe quantum dots
D. Schikora,S. Schwedhelm,Donat Josef As,Klaus Lischka,Dimitri Litvinov,Andreas Rosenauer,Dagmar Gerthsen,M. Strassburg,Axel Hoffmann,Dieter Bimberg +9 more
TL;DR: In this paper, the authors investigated the growth kinetics of the self-assembled formation of coherently strained CdSe islands and found that two distinctly different types of islands are formed in succession.
Journal ArticleDOI
Origin and consequences of a high stacking fault density in epitaxial ZnO layers
TL;DR: In this paper, the authors applied transmission electron microscopy to study ZnO grown by metalorganic vapor phase epitaxy on Al2O3(0001) substrates and found that the defect structure of the material is dominated by an extraordinary high density of small stacking faults with extensions between 5 and 25 nm which induce a bright small-scale speckle contrast under weak-beam imaging conditions.
Journal ArticleDOI
Coexistence of planar and three-dimensional quantum dots in CdSe/ZnSe structures
M. Strassburg,Th. Deniozou,Axel Hoffmann,R. Heitz,U. W. Pohl,Dieter Bimberg,Dimitri Litvinov,Andreas Rosenauer,Dagmar Gerthsen,S. Schwedhelm,Klaus Lischka,D. Schikora +11 more
TL;DR: In this paper, two well distinguishable classes of nanoscale islands were identified in CdSe/ZnSe quantum dot structures by optical spectroscopy and transmission electron microscopy.
Journal ArticleDOI
Control of the electronic properties of CdSe submonolayer superlattices via vertical correlation of quantum dots
Igor Krestnikov,M. Straßburg,M. Caesar,Axel Hoffmann,U. W. Pohl,Dieter Bimberg,N. N. Ledentsov,P. S. Kop’ev,Zh. I. Alferov,Dimitri Litvinov,Andreas Rosenauer,Dagmar Gerthsen +11 more
TL;DR: In this article, structural and optical properties of submonolayer CdSe/ZnSe superlattices grown with varying thickness of the ZnSe spacer layer are studied.
Journal ArticleDOI
Character of the Cd distribution in ultrathin CdSe layers in a ZnSe matrix
TL;DR: In this article, the character of Cd distribution and the morphology of ZnSe layers with nominal thicknesses between 0.7 and 3.6 ML were studied by conventional TEM and high-resolution transmission electron microscopy (HRTEM) using plan-view and cross-section TEM samples.
