Performance improvement of MOCVD grown ZnGa2O4 based NO gas sensors using plasma surface treatment
Applied Surface Science · 2023-07-01 · 32 citations
articleOpen accessGas sensors are essential devices in various industrial and environmental monitoring applications. Nitric oxide (NO) is a harmful gas that is produced in various combustion processes and is associated with air pollution and respiratory diseases. Zinc gallate (ZnGa2O4) has shown promising results as a material for NO gas sensing applications. Previously, the performance of NO gas sensors based on ZnGa2O4 epilayers was not substantial. However, there is potential for further improvement by optimiz…

articleOpen accessFor semiconductor device applications such as FinFET, MEMS, 2D materials, and wide bandgap materials, reliability is one of the most powerful key factors for commercialization in the industry. ZnGa2O4 deep ultraviolet (DUV) photodetectors (PDs) have been studied for their reliability and hence have been examined using the accelerated life test (ALT), which has shown the poor reliability of the device and device degradation such as high leakage current and poor rise time falling time (Tr/Tf) rati…
