“…Usually, ZnO seed layer are prepared using zinc acetate dehydrate as the precursor (Greene et al 2005;Park et al 2016;. Well seed alignment significantly influences the growth of ZnO nanorod (Yu et al 2017). In order to obtain well seed alignment, thermal treatment is needed at range of 150 o C to 200 o C for complete decomposition of zinc acetate to ZnO.…”

“…Different precursors may result in different morphology and shape which may be attributed to different reaction pathways, solubility of the precursor, and basicity of the solution which influenced the crystal nucleation and growth of ZnO nanorod (Yun et al 2010). Moreover, it can be predicted that the diameter of nanorod strongly depends on diameter of seed and the length of nanorod depends on the growth time and temperature (Hassanpour et al 2017;Jeong et al 2011;Park et al 2016;Yu et al 2017). Additive of ethylene glycol (EG) assists the crystal of ZnO nanorod to grow homogenously attributed to its good dispersibility and glutinosity (Long et al 2008).…”

Zinc oxide is a unique n-type semiconducting material, owing to wide bandgap of ~3.37 eV, non-toxic, bio-safe and biocompatible with high isoelectric point of ~9.5, make it as promising biomaterial to be utilized as sensing matrix in biosensor applications. In addition, ZnO that possess high electron affinity provide a good conduction pathway for the electrons hence result in significant electrical signal change upon detection to target biomolecules. Moreover, high surface area of ZnO nanorod enhance immobilization of enzymes, hence, increase the device performance. Field effect transistor (FET)-based biosensor offer simplicity in handling and label-free, has also become research topic among researchers for novel biosensor development. This review aims to explore the preparation of ZnO nanorod using hydrothermal method and investigate the fabrication of ZnO nanorod-based FET biosensor. Thus, contribute to enhance understanding towards biosensor development for health monitoring, especially based on FETs structure devices.

“…Yu et al (Yu et al, 2017) used a N-type Si (100) wafer and deposited thin ZnO films (for 10, 20 and 30 min) via PLD, as shown in Figures 6D-F. For nanorod's growth, they used Zinc metal foils as a source of formamide solution and the bath temperature was kept constant at 65°C for 24 h and annealed at 600°C for 1 h.…”

Nanostructured ZnO has gained a lot of interest as a suitable material for various applications, especially sensing, energy conversion, and storage. ZnO nanostructures can be synthesized in several ways. It is one of the materials that can be prepared in a variety of morphologies including hierarchical nanostructures. This review article presents a review of current research activities on the growth of ZnO Nanorods. The article covers various water-based routes of synthesis and is further characterized by the type of substrate used for the growth. The growth factors involved in the hydrothermal and chemical bath deposition methods are discussed. These factors include the variety of precursors, time, temperature, and the seeding method employed. At the end, applications such as gas sensing and improvement in Opto-electric properties are discussed.

“…Since 1948, the demand of low-cost and environment-friendly fabrication processes for nanostructures leads to the development of a hydrothermal process [13]. This method plays an important role in producing crystalline 1D-ZnO on various substrates including glass, silicon, and polymer [14,15]. Furthermore, the nanostructures' properties can be tuned by varying different parameters of a hydrothermal process such as the reaction time, temperature, concentration of a precursor, and the pH value of the solutions.…”

Design of Experiment (DOE) has been used for the optimization of a hydrothermal growth process of one-dimensional fluorine-doped zinc oxide (1D-FZO). Box-Behnken design was used in the DOE which includes three design points on each of the synthesis condition parameters. The condition parameters were the gold sputtering time (10 s, 15 s, and 20 s), hydrothermal reaction time (3 hours, 6.5 hours, and 10 hours), and hydrothermal temperature (50°C, 75°C, and 100°C). This statistical method of DOE was used to study the effects of these hydrothermal conditions on the quality of 1D-FZO produced. Au nanoparticles were used as the catalyst to enable the growth of the 1D-FZO. The XRD and EDX analysis confirmed the formation of polycrystalline FZO with the presence of fluorine, zinc, and oxygen elements. SEM observations indicated that the sputtering time of the Au nanoparticles has significant effect on the morphology and growth process of 1D-FZO. The lowest resistance value of 22.57 Ω was achieved for 1D-FZO grown with the longest Au sputtering time at growth temperature below 100°C.
