Synthesis of textured discontinuous-nanoisland CaCoO thin films.

Controllable engineering of the nanoporosity in layered CaCoO remains a challenge. Here, we show the synthesis of discontinuous films with islands of highly textured CaCoO, effectively constituting distributed nanoparticles with controlled porosity and morphology. These discontinuously dispersed textured CaCoO nanoparticles may be a candidate for hybrid thermoelectrics.
