摘要:
The invention relates to a detector for detecting highly toxic gaseous or vaporized hazardous substances or warfare agents. In order to be able to detect such substances quickly and easily at ambient temperature, a substrate comprising a hydrogen (H)-terminated or hydrogenated surface is used as a warfare agent detector. The substrate is equipped with a measuring instrument for measuring shifts of surface charges on the hydrogen (H)-terminated or hydrogenated surface. The substrate is made of a semiconductor material or a non-conductive material that has surface conductivity.
