- Single-crystalline wurtzite CdS nanowires underwent gas-phase substitution to form unique
superlattice cubic Cu1.8S (digenite) and hexagonal Cu2S (chalcocite) structures, using thermal
evaporation of CuCl2 at 500~600 ˚C. The Cu1.8S nanowires consisted of superlattices along the<111> direction, with controlled growth direction (, , , ) and superlattice periods of 1.6 and
1.9 nm. As the temperature decreased, the growth direction evolved from  to the higher surfaceenergy
 or  directions, with longer superlattice periods. The Cu2S nanowires also exhibited
a superlattice along the  growth direction, with a periodicity of 2.7 nm and could be irreversibly
converted into superlattice Cu1.8S by electron-beam irradiation.
