“…In addition, Greene et al (2005) has confirmed that acetate-derived seed layer significantly improves vertical alignment of grown ZnO nanorod compared to unseeded and zinc nitrate-derived seed layer. Increasing the number of coating layers will reduce their grain boundaries hence providing path for electrons to move and result in increased conductivity, also shown in Figure 3 (Khan et al 2017;.…”

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.

“…Absorption bands below 1000 cm À1 are due to interatomic vibrations of metal oxides. 26 The absorption bands observed between 480 cm À1 and 580 cm À1 correspond to the Zn-O stretching mode. 27 The n-type conductivity of undoped ZnO is due to the presence of impurities such as hydrogen (H), which is present in almost all growth environments.…”

“…Dahnoun et al, [17] obtained crystalls with the size ranging from 23 nm to 47 nm and the transmittance of 80 % in the ZnO films they produced. Khan et al [18] achieved a transmittance of 80 % in multi-layer ZnO films and observed that the multilayers showed better transparent conductive performance than single-layer ZnO. Patil et al, [19] evaluated the gas sensing performance of ZnO film produced at different temperatures.…”

In this study, CdZnO films prepared at different ratios of dopants (CdO:ZnO = 5:5, CdO:ZnO = 6:4, and CdO:ZnO = 8:2) were coated on glass surface by using the sol-gel spin coating technique. After this process, surface structure and optical properties of the CdZnO films was investigated by atomic force microscopy (AFM) and UV-Vis spectroscopy. The surface structure of the CdZnO films depended on the content of ZnO and CdO in the films. Low percentage of CdO films were very similar to the ZnO film but higher amount of CdO resuted in granular structures together with pure structure of ZnO in the films. Eg values of produced CdZnOs depended on the additions of CdO and ZnO. The obtained Eg values of the produced CdO:ZnO = 5:5 (S3), CdO:ZnO = 6:4 (S4), and CdO:ZnO = 8:2 (S5) films are 2.5 eV, 2.49 eV, and 2.4 eV, respectively.
