Electronic Ceramics

About

The research group “Electronic Ceramics” explores and develops novel, generally multi-component, complex oxide functional material systems. Our major objective is to bridge their in-depth crystal chemical understanding to compositional and process design including grain-boundary engineering. Focused scientific interest and consideration are currently devoted predominantly but not exclusively to perovskite-type based higher-order solid solutions and composites, where pronounced effects of enhanced configuration entropy and ionic non-stoichiometry determine resistive and dielectric materials response.

Research Topics

High-Entropy Ferroelectrics & Microwave Dielectrics for 5G-Applications.
Ceramic Target Materials for the Deposition of High-Entropy Thin Film Memristor Devices.
Ecologically Sustainable Fabrication of Ceramics for Electrical High-Temperature Energy Storage Applications.
Internal Barrier-Layer Capacitor (IBLC) Materials with Colossal Dielectric Permittivity.
Development of Dielectric Ceramics with Oxygen-permeable Grain-Boundary Phase for Reduction Resistant Multilayer Varistors, Thermistors or Capacitors.
