  2. 21. Scandium Nitride Thin Films for Thermoelectrics

    Author : Sit Kerdsongpanya; Per Eklund; Björn Alling; Lars Hultman; Gunilla Wingqvist; Heiner Linke; Linköpings universitet; []
    Keywords : ;

    Abstract : Thermoelectric devices are one of the promising energy harvesting technologies, since they can convert heat (i.e. a temperature gradient) to electricity. This result leads us to use them to harvest waste heat from heat engines or in power plants to generate usable electricity. READ MORE

  4. 22. Growth and Characterisation of Non-linear Ferroelectric Heterostructures

    Author : Khaled Khamchane; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : High dielectric constant or ferroelectric materials are needed for a range of devices, non-volatile ferroelectric computer memories, NVFRAMs, microwave devices utilising the non-linear polarisation as a function of electric field, or other microwave applications. High dielectric constant and low losses can be achieved in single crystals of ferroelectrics. READ MORE

  5. 23. Electromagnetic studies of the continental crust in Sweden

    Author : Mehran Gharibi; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : Plane-wave electromagnetic methods are powerful tools for probing the earth from the surfaceto depths of a few hundred kilometers. The airborne VLF technique is widely used to map theelectrical conductivity variations of shallow geological structures. READ MORE

  6. 24. Charge Density Waves and Alkali Metal Intercalation in Layered Materials

    Author : Inger Ekvall; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; charge density waves; STM STS; W tips; alkali metal intercalation;

    Abstract : In this thesis the following issues are discussed: 1. Fundamental properties of two polytypes of TaS2 studied by scanning tunneling microscopy (STM) and spectroscopy (STS). 2. The influence of Na intercalation on charge density waves (CDW's) in 1T-VSe2 and 4Hb-TaS2 studied by STM and STS. READ MORE

  7. 25. The transistor, with emphasis on its use for radio frequency telecommunication

    Author : Ted Johansson; Dag Sigurd; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis is about transistors, integrated circuits and techniques to fabricate electronic devices in semiconductor materials. The most important application area for the transistors studied in the thesis is radio frequency telecommunication. READ MORE
