摘要：

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 parallel-to {00.1}CdSe and [110]Au parallel-to [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.
