  1. 11. Fabrication, Simulation and Performance of Ultra-Thin Silicon Detectors-Development of a Detection System for Living Cell Irradiation

    Författare :Naseem Salim; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2014:Abdel; micro-fabrication technology; ultra-thin silicon detector; single ions; SIHF; ΔE detector;

    Sammanfattning : For the development of a Single–Ion Hit Facility (SIHF) for living cells irradiation at the Lund Ion Beam Analysis facility (LIBAF), newly developed pre-cell detectors have been investigated. These detectors can determine the number of ions reaching the sample. Central to the thesis is their fabrication and characterization. LÄS MER

  3. 12. Micro-Optical Elements in Gallium Arsenide and Diamond: Fabrication and Applications

    Författare :Mikael Karlsson; James R. Leger; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Materialvetenskap; Materials Science;

    Sammanfattning : This thesis mainly treats the fabrication and applications of micro-optical elements in the semiconductor materials gallium arsenide (GaAs) and diamond.The recent trend in high-capacity data transfer using light as the information carrier creates new demands on the optoelectronic systems, such as small size, low cost and the integration of many components.

  4. 13. Nano and Micro Patterned Organic Devices : From Neural Interfaces to Optoelectronic Devices

    Författare :Tobias Nyberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis describes fabrication methods for optoelectronic devices (light emitting diodes (LEDs) and photodiodes) and structures for neural interfacing (neural electrodes and nerve guidance structures) using semiconducting and conducting organic materials as the active elements. Special importance has been attached to the patterning and processing of these devices. LÄS MER

  5. 14. Fabrication of Polymer Electrolytes for 3D-Microbatteries

    Författare :Bing Sun; Daniel Brandell; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 3D-microbattery; Polymer electrolyte; Multifunctional monomer; Polyetheramine; Polycarbonate; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : Pressing demands on electrical energy storage require high power and high energy density rechargeable batteries with improved safety, reliable performance and low cost. This has led to reconsiderations in the choice of battery chemistry and battery design. LÄS MER

  7. 15. Micro- and Millimeter Wave CMOS Beamforming Receivers

    Författare :Andreas Axholt; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; beamforming; CMOS; front-end; microwave; millimeter wave; phase-locked loop; phased-array;

    Sammanfattning : The available bandwidth in wireless communication systems, such as the 802.11 family, is very limited. Together with the ever increasing data traffic, this causes problems. New possibilities are, however, available thanks to wide license-free bandwidth allocated at higher frequencies. LÄS MER
