Properties of nanostructured ZnO thin films synthesized using a modified aqueous chemical growth method

Research and development of nano-sized Zinc Oxide (ZnO) has recently received great attention due to its remarkable properties such as large exciton binding energy of 60 meV, extraordinary photosensitivity, nontoxic nature, wide bandgap and the fact that it is a low cost material w...

Thin Films of Barium Strontium Titanate from the Viewpoint of Light-Based Applications

In this paper we report results from optical transmittance spectroscopy complemented with data on structure from XRD measurements to determine optical properties of a series of as-deposited and annealed (at 900 C) BaSrTiO3 (BST) thin films deposited by RF magnetron sputtering. The memb...

Identifikace elektrických vlastností podle tloušťky v vrstvě oxidu zinečnatého dopovaného hliníkem naprašovaného při 100 ° C

This work presents a detailed study of aluminium-doped zinc oxide thin films sputtered at 100 °C, with a focus on the correlation between structural and electrical properties. The structural properties are identified by SEM microscopy and X-ray diffraction, while the electrical properties ...

Influence of oxygen on the resistivity of co-sputtered transparent AZO films

In the present work co-sputtering from ceramic and metallic targets is used to reduce the oxygen content in aluminium doped zinc oxide. Films with thickness between 200 and 220 nm are sputtered at 100 and 250 °C and investigated by X-ray diffraction, energy dispersive spectros...
