Abstract
Semiconductor materials demand is increased in recent years, due to new emerging technologies. There is need to find the alternate for silicon in electronics industry, as silicon is brittle in nature and has low efficiency, which makes it unsuitable for transparent and flexible device. Zinc oxide (ZnO) is emerging as popular choice of researchers due to its wide range of properties, abundancy and non-toxicity. This work explores the properties of ZnO thin film deposited on Polyethylene terephthalate (PET) substrate using RF Sputtering Technique. This technique deposited film in controlled environment with better precision and uniformity. Fourier Transform-IR (FT-IR) Spectroscopy confirms the presence of desired covalent bonds of zinc and oxygen. Energy Dispersive X-Ray (EDX) mapping was done to confirm the presence of functional groups in film. Optical properties of substrates were determined by ultraviolet-visible spectrophotometer (UV) absorption spectra and band gap calculated was around 3.1eV. Surface morphology was studied via atomic force microscopy (AFM) and surface roughness measured was around 3.5nm. Structural properties were studied by X-ray Diffraction (XRD). High-quality crystal structure was obtained in this work. Scanning electron microscopy (SEM) results confirmed crack free surface with proper adhesion of ZnO layer on ITO. Surface topology and morphology results confirmed uniform deposition and grain formation. This film shows promising results for optoelectronics devices like sensors, organic LED’s, photovoltaics, solar cells.
