Abstract
An Attempt to Study MoO3-Like TCO Nanolayered Compound in Terms of structural and Ethanol Sensitivity Application
Highlights
During the last years, the semiconductors based on metal oxides have known many interests in the research as well as in the field of the application
Several metal oxides have been tested as gas sensors such as ZnO [4], In2O3 [5], SnO2 [6]

Summary
The semiconductors based on metal oxides have known many interests in the research as well as in the field of the application. It is found that MoO3 is a n-type semiconductor this property is related to oxygen vacancies in this binary compound. The present work is devoted essentially to the study of ethanol detection by MoO3 sprayed thin film. Molybdenum oxide thin films were deposited on glass substrates at 460 °C using 10-2M Ammonium molybdate tetrahydrat [(NH4)6Mo7O24.4H2O] aqueous solution.
