摘要：
The electrical resistivity of the layered semiconductor CuFeTe2 is created in response to oxygen concentration intercalated into the van der Waals gaps. An oxygen gas sensor operating around room temperature has been fabricated using this property. The resistivity response to oxygen has been improved by the use of crystal grains of uniform size. The specimen consisting of grains with diameters of 20 approximately 53 mum responds to 20% oxygen mixed into nitrogen in 2 min.
