“…To further validate the growth mechanism of Cu 2- x Se, we carried out theoretical calculations for Cu 2- x Se formation with and without the Br-termination. Copper selenide Cu 2- x Se is in the antifluorite structure and its space group is F 4̅3 m (Figure a). The face-centered matters usually tend to nucleate and grow into twinned and multiply twinned particles with their surfaces bounded by the lowest-energy {111} facets .…”

Nanocubes of copper selenide (Cu2-x Se) have been synthesized through an electrochemical crystallization method using cetyltrimethylammonium bromide (CTAB) as the structure directing agent. The shapes of Cu2-x Se nanocubes can be controlled by the adsorption effect of CTA+ hydrocarbon chain and Br− ion on the facets of the Cu2-x Se crystals. First-principle quantum chemical calculations indicate that the preferential adsorption of bromide onto the {100} facets of Cu2-x Se crystals results in the final cubic shape. The ability to generate Cu2-x Se nanostructures with well-defined morphologies not only provides potential application of Cu2-x Se nanocubes in photoelectric devices but also provides a great opportunity to systematically study the relationship between their properties and geometric shapes.
