Use of chemically sensitive semiconductor material containing chalcogens or chalcogenides for detecting gaseous and vaporous analytes in gases

摘要

Use of a chemically sensitive semiconductor material (2) containing chalcogens or chalcogenides for detecting gaseous and vaporous analytes (6) in gases is new. The detection of the gases/vapors is based on a change of the electronic, dielectric, mechanical/acoustic or optical properties of the semiconductor material. An Independent claim is also included for a sensor with a chemically sensitive semiconductor material as transducer element for detecting gaseous and vaporous analytes (6) in gases. Preferred Features: The semiconductor material contains tellurium or one of the following binary alloys: Na-Te, AK-Te, Rb-Te, Cs-Te, Si-Te, Ge-Te, Sn-Te, As-Te, Sb-Te, Bi-Te, S-Te, Se-Te or Te-Te.
