Synthesis of CuInSe(2) nanocrystals with trigonal pyramidal shape

J Am Chem Soc. 2009 Mar 11;131(9):3134-5. doi: 10.1021/ja8080605.

Abstract

The synthesis of monodisperse chalcopyrite (tetragonal) CuInSe(2) nanocrystals is reported. The nanocrystals have trigonal pyramidal shape, and they exhibited a common crystallographic orientation when drop-cast onto carbon substrates. A crystallographic model for the nanocrystals was developed. The nanocrystals are bounded by one polar {112} surface facet and three nonpolar {114} surface facets.
