Analysis of the measured IU-characteristics confirm the overlapping of geometry- and material-based field enhancement. The degradation of DLC covered needles appears slower than for DLC layers on planar geometries.enfalsefield emissionspace applicationtetrahedral amorphous carbonGeometryDegradationTungstenCarbon dioxideNeedlesDiamond-like carbonCoatingsNanoelectronicsDiamond-like Carbon600 Technik, Medizin, angewandte Wissenschaften::620 Ingenieurwissenschaftenconference paper
