However, the performance at ambient pressure remains largely unexplored. In this study GOS-emitters are characterized in nitrogen and air at atmospheric pressure, and compared with their vacuum characteristics. For this purpose, lifetime and IV-characteristics measurements are shown. Furthermore, the GOS-emitter was operated as an ionization source for ion mobility spectrometry (IMS) at ambient conditions.}, note = {}, institution = {Universität der Bundeswehr München, Fakultät für Elektrotechnik und Informationstechnik, EIT 2 - Institut für Physik, Professur: Düsberg, Georg}, }
