Název v původním jazyce

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)

Popis výsledku v původním jazyce

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 (AZO) thin films were deposited by pulsed laser deposition (PLD) on commercial gold-based interdigitated electrodes (IDE) on glass substrates. Surface morphology and structure were characterized using Correlative Probe and Electron Microscopy (CPEM), combining Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM) to perform spatially correlated measurements. Longer deposition resulted in the growth of larger crystals and thicker ZnO layers, while Al doping only slightly affected grain size and reduced growth rate. Optical and optoelectronic properties were investigated by photothermal deflection (PDS) and photocurrent spectroscopy (PCS). The mobility edge was found to lie approximately 0.3 eV below the band gap. Space-charge-limited currents were observed at low voltages. Persistent photoconductivity indicates potential issues with charge transport.n
