Oxide semiconductor gas sensors have been widely used to detect hazardous gases and their...
Metal oxides represent a vast class of materials of interest for various scientific communities, ranging from physics to chemistry, from material science to engineering. The majority of metal oxides are in principle sensitive to gases. However, in order to be performing materials for the fabrication of chemical sensors, they need to fulfill specific requirements such as sensitivity,...
One dimensional (1D) nanostructures of metal oxides and their derivatives are very useful for the gas sensing applications due to their high sensitivity, quick response, and responsiveness to a wide range of target gases. However, their controlled integration on low-power and ultra-compact MEMS micro-heating platform has been very challenging due to the difficulty of their handling and...
Introduction
Gas sensors provide fast, real-time and in-situ information of gas species and concentration, playing a significant role in detecting hazardous and explosive gas in the environment. As an important semiconductor, In2O3 exhibits potential applications for gas sensors, such as for the detection of H2S owing to its nonstoichiometric chemical form due to O2 vacancy and...
