1. Thermally stable electrical contacts to 6H silicon carbide
Sammanfattning : Silicon Carbide (SiC) are at present being developed for use in high temperature (≥ 500◦C) and high-power environments under which conventional semiconductors can hardly perform. Thermally stable electrical contacts are essential to the ability of SiC to function under such extreme conditions. LÄS MER

Sammanfattning : .... LÄS MER
3. Electrical and optical properties of doped tin oxide films
Sammanfattning : .... LÄS MER
4. Effects of Corona and Ozone Exposure on Properties of Polymeric Materials for High Voltage Outdoor Applications
Sammanfattning : Despite the past four decades of service experiences with polymeric insulators in power systems all over the world, an adequate standard allowing for proper selection of polymeric materials for applications in high voltage outdoor environments has still been lacking. Therefore CIGRE Working Group D1. LÄS MER
5. Ground Monitoring using Resistivity Measurements in Glaciated Terrains
Sammanfattning : The most common method of monitoring and mapping groundwatercontaminants is to extract and analyse a number of groundwatersamples from wells in the investigation area. However, thereare a number of limitations with this type of point-wiseinvestigation, as it is hard to acquire an adequate picture ofa heterogeneous and anisotropic subsurface using a fewpoints.
