Scope of work

  • Mechanical and micro-structural analyses of structural and functional materials, components and devices
  • Environmental degradation in brittle materials and components (e.g. temperature and humidity)
  • Development of testing methods for brittle materials, microelectronic components and hybrid systems
  • Fracture mechanics and failure analysis of brittle solids: from single crystals to microelectronic ceramic systems (e.g. Si chips, wafers, thin film sensors, piezo-actuators, LTCCs, SOFCs)
