  3. 13. Nanostructured materials for gas sensing applications

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Kristina Buchholt; Linköpings universitet.; Linköpings universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : In this Thesis I have investigated the use of nanostructured films as sensing and contact layers for field effect gas sensors in order to achieve high sensitivity, selectivity, and long term stability of the devices in corrosive environments at elevated temperatures. Electrochemically synthesized Pd and Au nanoparticles deposited as sensing layers on capacitive field effect devices were found to give a significant response to NOx with small, or no responses to H2, NH3, and C3H6.

  5. 15. Silicon Carbide High Temperature Photodetectors and Image Sensor

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Shuoben Hou; KTH.; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon Carbide SiC ; high temperature; photodetector; photodiode; phototransistor; ultraviolet UV ; transistor-transistor logic TTL ; bipolar junction transistor BJT ; integrated circuit IC ; pixel sensor; image sensor; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Silicon Carbide (SiC) has the advantages of ultraviolet (UV) sensing and high temperature characteristics because of its wide band gap. Both merits make SiC photodetectors very attractive in astronomy, oil drilling, combustion detection, biology and medical applications. LÄS MER
