“…From the graph, the potential cut-off wavelength takes place from 370nm -385nm and no other peak was observed in the spectrum confirms that the synthesized are pure ZnO and its wide-band-gap is about 3.3eV. [17,18] The band gap energy can be evaluate by substituting the value of the absorption peak at a given wavelength in the following equation [19] Eg=hvg =hc/λg (1) Where h = 4.14x10 -15 eVs, c = 2.99x10 8 m/s, and λ is referred in Figure 6. around 1µm while the magnification range applied ranging from 10000X to 50000X in order to observe the difference surface morphology of the thin films.…”

Abstract. In fabricating Surface Acoustic Wave (SAW) biosensors device, the substrate is one of important factors that affected to performance device. there are many types of piezoelectric substrate in the markets and the cheapest is zinc Oxide substrate. Zinc Oxide (ZnO) with its unique properties can be used as piezoelectric substrate along with SAW devices for detection of DNA in this research. In this project, ZnO thin film is deposited onto silicon oxide substrate using electron beam evaporation (E-beam) and SolGel technique. Different material structure is used to compare the roughness and best piezoelectric substrate of ZnO thin film. Two different structures of ZnO target which are pellet and granular are used for e-beam deposition and one sol-gel liquid were synthesize and compared. Parameter for thickness of ZnO e-beam deposition is fixed to a 0.1kÅ for both materials structure and sol-gel was coat using spin coat technique. After the process is done, samples are annealed at temperature of 500C for 2 hours. The structural properties of effect of post annealing using different material structure of ZnO are studied using Atomic Force Microscopic (AFM) for surface morphology and X-ray Diffraction (XRD) for phase structure.

“…, and ZnO NPs (synthesized as reported by Chieng et al [17]) are used and PFE:BNDI:ZnO solutions were spin coated at 1500 rpm onto the PEDOT:PSS layer. Finally, the Al electrode (80 nm) was deposited by using a shadow-mask with vacuum thermal evaporator attached to an MBRAUN 200B glove box system with a depositing rate of 0.5Å/s at 3 × 10 −6 mbar pressure.…”
