Gas sensing performance of α-, α/β-, and β-Ga2O3 polymorphs
Source abstract
Abstract
This paper reports the detection of SO 2 , NH 3 , and CO gases using Ga 2 O 3 polymorphs. The α-Ga 2 O 3 , α/β-Ga 2 O 3 , and β-Ga 2 O 3 sensing materials were prepared using the hydrothermal method, followed by calcination at different temperatures ranging from 550 °C to 950 °C. The gas sensing properties were measured and analyzed based on the polymorphism-induced physicochemical properties of the sensing materials. Different Ga 2 O 3 polymorphs showed distinct sensing properties, and factors contributing to this preferential gas detection behavior are discussed in detail. The proposed gas sensing mechanisms were discussed. Notably, the gas sensing performance of the α/β-Ga 2 O 3 -based sensor is reported here for the first time.
