Abstract
The experiment successfully synthesized a ternary phase thin film ZnGa_2O_4 through annealing and liquid metal diffusion on a zinc oxide substrate. Characterization via X-ray diffractometry (XRD) confirmed its atomic arrangement as ZnGa_2O_4 spinel, consistent with the crystal structure (JCPDS 71-0843). Chemical composition analysis was carried out using X-ray photoelectron spectroscopy (XPS). At the same time, the microstructure and surface morphology were examined using optical microscopy (OM), atomic force microscopy (AFM), and transmission electron microscopy (TEM). Subsequent light sensing tests revealed promising optoelectronic properties. The photoresponse current was measured at 2.35×10^(-5) A, with a response time of 0.54 seconds. These results underscore the potential of the ZnGa_2O_4 thin film for various optoelectronic applications. Photodetector devices are fabricated and characterized, revealing ZnGa_2O_4 photosensitive nature with distinct performance metrics, making it promising for photodetector applications. This research offers a scalable method for two-dimensional gallium-group semiconductor synthesis, holding potential for diverse optoelectronic applications.
