Description
The state of the art NO2 gas sensors suffer from a trade-off between sensitivity, reversibility, and selectivity. This thesis focuses to develop highly sensitive NO2 gas sensors with superior selectivity based on layered molybdenum trioxide and its heterostructures. Through a combination of advanced materials synthesis and characterisation techniques, ultrasensitive NO2 gas sensors based on different morphologies of molybdenum trioxide, including nanoribbons, large-sized single crystalline flake and heterostructures have been demonstrated. This thesis lays the foundation for developing a potential sensing platform based on molybdenum trioxide to enable monolithic, scalable and integrable sensing technologies.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
