Abstract:

Gallium oxide films for sensing gas comprise GaOand have a porosity of at least about 30%. Such films can be formed by coating a substrate with a solution comprising: a gallium salt and a porogen comprising an organic compound comprising a hydrophilic chain and a hydrophobic chain; and heating the substrate to a temperature in the range from about 400 C. to about 600 C. while exposing the substrate to an oxygen-containing source to convert the gallium salt to a gallium oxide.
