Synthesis of textured discontinuous-nanoisland Ca3Co4O9 thin films

Controllable engineering of the nanoporosity in layered Ca3Co4O9 remains a challenge. Here, we show the synthesis of discontinuous films with islands of highly textured Ca3Co4O9, effectively constituting distributed nanoparticles with controlled porosity and morphology. These discontinuously dispersed textured Ca3Co4O9 nanoparticles may be a candidate for hybrid thermoelectrics.

Automated summary

This study demonstrates a method to synthesize distributed nanoparticles with controlled porosity and morphology, which have the potential to be used as hybrid thermoelectrics.
