Abstract

CdSe quantum dots, electrodeposited epitaxially on {111} gold substrates, were studied by high resolution transmission electron microscopy (HREM). Images corresponding to wurtzite {10.0}_CdSe and {11.0}_CdSe as well as {220}_Au and 1 3{422}_Au, directly confirmed the epitaxial relationships previously shown by electron diffraction, namely {111}_Au{norm of matrix}{00.1}_CdSe and 〈110〉_Au{norm of matrix}〈11.0〉_CdSe. Further analysis of the HREM images by optical diffraction (selected-area nanodiffraction) provided structural information on the orientation of single nanocrystals with respect to the substrate and allowed detection of slight misalignments of individual quantum dots.
