BPN936: Hafnium Diboride-Based Gas Sensor

While the transition metal oxides and dichacogenides have been extensively used as sensing materials, the transition metal diborides (TMDBs) have not been explored to any appreciable extent. As a class, TMDBs possess a variety of unique properties, including very high melting points, high thermal and electrical conductivities, and good corrosion resistances, and therefore hold promise as materials for the sensing of harmful gases or at elevated temperatures. This project seeks to probe the gas sensing behavior of TMDBs to a variety of industrially-relevant gases, provide insight into the gas sensing mechanisms, and develop TMDB-based structures for enhanced gas sensing performance.
