p-doped silicon field emitters were studied experimentally to assess their usefulness in multibeam electron lithography. Both individual emitters and emitter arrays were fabricated from single crystal Si wafers with several doping levels. Current-voltage curves were measured for different temperatures and illumination conditions. The typical plateaus in the(More)
Information dissemination in pure Vehicular Ad Hoc NETworks (VANETs) such as ITS-G5 becomes problematic when the network is sparse. In situations where the number of vehicles, that can act as a communication node, is insufficiently low, e.g. in rural areas, during nighttime or because of a low market penetration of the technology in the early years of(More)
Research in the field of Intelligent Transport Systems (ITS) is emerging, motivated by the need for improved road safety and environmental concerns. In Europe, many traffic fatalities occur each year and the transportation industry is one of the largest emitting industry of greenhouse gases. These problems can be mitigated by the use of vehicular networks,(More)
