Temperature and Ambient Band Structure Changes in SnO2 for the Optimization of Hydrogen Response
Autor: Petros-Panagis Filippatos, Anastasia Soultati, Nikolaos Kelaidis, Dimitris Davazoglou, Maria Vasilopoulou, Charalampos Drivas, Stella Kennou, Alexander Chroneos
Publikováno v: Inorganics, Vol 11, Iss 3, p 96 (2023)
Tin dioxide (SnO2) is one of the most used materials for sensing applications operating at high temperatures. Commonly, “undoped SnO2” is made by precursors containing elements that can have a deleterious impact on the operation of SnO2 sensors.
