Optical, electrical and surface properties of bare and Al-doped nanocrystalline ZnO (AZO) thin films grown by pulsed laser deposition (PLD) on commercial interdigital electrodes (IDE)

Zinc oxide (ZnO) is a low-cost, environmentally friendly material with unique optical properties and a wide variety of nano- and microstructures, making it attractive for applications in energy conversion, scintillators, photocatalytic wastewater treatment, electrochemical energy storage, and sensing. In this work, nominally undoped and Al-doped nanocrystalline ZnO thin films were deposited by pulsed laser deposition (PLD) on commercial gold-based interdigitated electrodes (IDEs).
