Abstract Scope |
Nanoengineering approach has been applied on thin films of Al-doped ZnO (AZO) prepared by several techniques to enhance their thermoelectric performance.
Insertion of artificial nanodefects has been considered with the purpose of depressing thermal conductivity (k) and enhancing figure of merit (ZT).
Several approaches have been tried:
(i) insertion of hydroquinone nanolayers in AZO films prepared by atomic layer deposition (ALD): kALD (300 K) = 3.56 W/m×K ;
(ii) addition of polymetylmetacrilate (PMMA) particles to AZO films prepared by multi-beam multi-target matrix-assisted PLD (MBMT/MAPLE-PLD): kMAPLE (300 K) = 5.9 W/m×K ;
(iii) formation of nanopores in AZO films prepared by Mist-Chemical Vapor Deposition (Mist-CVD): kporous (300 K) = 0.60 W/m×K;
(iv) dispersion of Al2O3 nanoparticulate in AZO films prepared by surface-modified target PLD: knanoAl2O3 (300 K) = 3.98 W/m×K .
All these successful examples highlight the promise of nanostructured AZO films for future energy harvesting applications.
