We will show that by enhancing the polarization "randomness" in the ferroelectric polymers, a large electrocaloric effect (ECE) can be obtained in these polymers.
Their topics include measuring nucleation and growth processes, analyzing the evolution of surface roughness, modeling thin film deposition processes based on real-time observation, phase transition in colloidal crystal thin films, thin film growth for thermally unstable noble-metal nitrides by reactive magnetron sputtering, electronic properties and adsorption behavior of thin films with polar character, understanding substrate plasticity and buckling of thin films, the electrocaloric effect in ferroelectric polymer films, and network behavior in thin films and nanostructure growth dynamics.
