H2S-sensing in the ppb regime with ZnO nanowires — •Florian Huber, Sören Riegert, Manfred Madel, and Klaus Thonke — Institute of Quantum Matter / Semiconductor Physics Group, Ulm University
The detection of hydrogen sulfide (H2S) plays a crucial role in several medical applications. On the one side it indicates different diseases such as asthma, on the other side it is used for therapeutic purposes, e.g. as so called slow releasing H2S-donors. However, the detection of small amounts of this gas is still a challenge, and especially for the analysis of the breath of patients a fast sensing method is needed.
In this project we investigate the electrical behaviour of ZnO nanowires towards H2S detection in order to develop a fast and very sensitive sensor. The goal is the detection of H2S concentrations in the lower ppb regime. Furthermore, the response of the nanowires to other gases, especially towards oxygen, is investigated in order to realize a breath sensor for medical use.
