  2. 6. Design, Fabrication and Optimization of Thermal Radiation Detectors Based on Thin Polymer Membranes

    Author : Claes Mattsson; Hans-Erik Nilsson; Göran Thungström; Ylva Bäcklund; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal detector; Polymer; Membrane; SU-8; Electronics; Elektronik;

    Abstract : The number of applications in which infrared radiation sensors are used is increasing. In some applications, the cost of the sensor itself is an issue, and simple solutions are thus required. In this thesis, the investigations have related to the use of thin polymer membranes in thermal infrared sensors, such as bolometers and thermopiles. READ MORE

  4. 7. Alkali Release and Effects on Biomass Thermal Conversion Processes

    Author : Yaxin Ge; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Co-conversion; Alkali; Biomass; bed material; thermal conversion; online measurements;

    Abstract : High alkali content is an important feature of biomass, and it has a series of implications for thermal conversion processes. This thesis focuses on the release of alkali during various biomass thermal conversion processes, including biomass pyrolysis, char gasification, co-conversion of different types of biomass, and thermal conversion of biomass mixed with fresh and used bed materials.

  5. 8. Electronic Properties of Diamond

    Author : Markus Gabrysch; Jan Isberg; Mats Leijon; Johan Hammersberg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; CVD diamond; wide-bandgap semiconductor; time-of-flight; pair-creation energy; electronic devices; detector; Elektronik; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik; Electricity; Esp The Study Of Transients and Discharges; elektricitetslära; ssk studiet av transienter och urladdning;

    Abstract : Diamond is a semiconductor with many superior material properties such as high breakdown field, high saturation velocity, high carrier mobilities and the highest thermal conductivity of all materials. These extreme properties compared to other (wide bandgap) semiconductors make it desirable to develop single-crystalline epitaxial diamond films for many electronic device and detector applications.

  6. 9. Pulse and hold switching current readout of superconducting quantum circuits

    Author : Jochen Walter; David Haviland; Hans Mooij; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Josephson junction; readout; qubit; detector; frequency dependent damping; quantronium; phase-space; correlation analysis; Physics; Fysik;

    Abstract : Josephson junction qubits are promising candidates for a scalable quantum processor. Such qubits are commonly manipulated by means of sequences of rf-pulses and different methods are used to determine their quantum state. READ MORE

  7. 10. Engineering Multicomponent Nanostructures for MOSFET, Photonic Detector and Hybrid Solar Cell Applications

    Author : Asghar Jamshidi Zavaraki; Hans Ågren; Kevin J. Webb; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Epitaxial G rowth; Reduced Pressure Chemical Vapor Deposition; GeSnSiC; MOSFET; Photonic Detector; Resistivity; Phosp hor and Boron doping; Colloidal QDs Sensitized Solar Cell; Cd - free and Cd - based QDs; High Resolution Reciprocal Lattice Map; High Resolution X - Ray Diffraction; High Resolution Transmission Electron Microscopy; High resolution Scanning E lectron Microscopy .;

    Abstract : Silicon technologyhas been seekingfor a monolithic solution for a chip where data processing and data communication is performed in the CMOS part and the photonic component, respectively. Traditionally, silicon has been widely considered for electronic applications but not for photonic applications due to its indirect bandgap nature. READ MORE
