W e reported CdSe quantum platelets having thicknesses corresponding to 7, 9, and 11 monolayers (MLs) of the wurtzite (WZ) crystal structure. We now correct our monolayer (ML) definition for the flat WZ CdSe nanocrystals having (11− 20) facets on the broad top and bottom surfaces (p 2240). We now define a ML (in [0001] zone axis, Figure 1) as the thinnest,(More)
We present a methodology for probing light-matter interactions in prototype photovoltaic devices consisting of an organic semiconductor active layer with a semitransparent metal electrical contact exhibiting surface plasmon-based enhanced optical transmission. We achieve high-spectral irradiance in a spot size of less than 100 μm using a high-brightness(More)
Images of knotting and linking are found in many of the drawings and paintings of Leonardo da Vinci, but nowhere as powerfully as in the six engravings known as the cartelle of the Accademia Vinciana. We give a mathematical analysis of the complex characteristics of the knotting and linking found therein, the symmetry these structures embody, the(More)
Reaction of Cd(OAc)2·2H2O and selenourea in primary-amine/secondary-amine cosolvent mixtures affords crystalline CdSe quantum platelets at room temperature. Their crystallinity is established by X-ray diffraction analysis (XRD), high-resolution transmission electron microscopy (TEM), and their sharp extinction and photoluminescence spectra.
