Comprehensive investigation of hydrogen-sensing properties of Pt/InAlP-based Schottky diodes

Improving hydrogen detecting performance of a Pd/n-LTPS/glass thin film Schottky diode with a TiO2 interface layer

“…However, hydrogen is a colorless, odorless, and extremely flammable gas with a lower explosive limit of 4% in air. Consequently, a fast and sensitive hydrogen sensor is needed for operating in hydrogen environments [4][5][6]. In the past, most of hydrogen sensors are built on Si [7][8][9][10] or III-V compound substrates [11][12][13].…”
