Abstract
Official abstract text for this publication.
A gas sensor device has a crystalline film of copper(I) bromide, wherein a crystal surface of the copper(I) bromide is formed of a stepped terrace having a flat face and a steep slope.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for fabricating a gas sensor device, the method comprising: forming a layered structure in which a copper(I) oxide underlying layer and a copper film are deposited in this order over a substrate; and forming a copper(I) bromide sensing film by enabling the layered structure to react with a copper(II) bromide solution. 2. The method as claimed in claim 1 , wherein a stepped terrace structure in which a (111) plane is dominant appears during formation of the copper(I) bromide sensing film.
