  4. 2. Electromagnetic Modeling with Complex Dielectrics : A Partial Element Equivalent Circuit Approach

    Author : Andreas Hartman; Jonas Ekman; Jerker Delsing; Frank Gronwald; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Abstract : Wireless communication systems have become an integral part of many complex systems in diverse areas of society, for the exchange of data in business and industrial settings. With the advent of Internet of Things (IoT) and wireless sensor network architectures, the tighter demands on interoperability between different devices are putting heavy requirements their ability to exchange data wirelessly among them reliably.

  5. 3. Tunnel Emitter Transistors

    Author : Erik Aderstedt; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TET; tunneling; siO2< sub>; tunnel emitter transistor; MOS; Ta2< sub>O5< sub>; silicon; high- #954; BICFET; dielectrics;

    Abstract : The Tunnel Emitter Transistor is based on the modulation of the tunnel current in a Metal Oxide Semiconductor (MOS) structure with an ultra-thin oxide layer. The modulation is accomplished by injecting charge to the oxide-semiconductor interface from a third terminal. READ MORE

  6. 4. Control of Defects and Subgrains in Epitaxial Perovskite Thin Films

    Author : Lars Ryen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thin film evolution; La0.70Ba0.30MnO3; epitaxial perovskite films; Keywords: TEM; dielectrics; EELS; SrTiO3; YBa2Cu3O7-x; superconductors; colossal magnetoresistance;

    Abstract : This work concerns the microstructure of epitaxial (001) perovskite thin films, studied by transmission electron microscopy (TEM), in particular high resolution TEM, electron energy-loss spectroscopy (EELS), and energy dispersive x-ray analysis. The perovskites exhibit interesting superconducting, dielectric, and magnetic properties. READ MORE

  7. 5. Computational framework for studying charge transport in high-voltage gas-insulated systems

    Author : Shailendra Singh; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drift diffusion equation; gaseous dielectrics; high voltage; gas discharge; low temperature plasma; streamer propagation;

    Abstract : Increasing demands in electric energy stimulates a shift in functional requirements to power distribution networks and pushes equipment manufacturers to develop highly optimized products where high rated parameters (e.g., energy, voltages) are combined with reduced geometrical dimensions of components.
