  2. 11. Fabrication and Characterization of Photon Radiation Detectors

    Author : Claes Mattsson; Hans-Erik Nilsson; Göran Thungström; Mikael Lindeberg; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Detectors; Posistion Sensitive Detectors; Electronics; Elektronik;

    Abstract : This thesis involves a study the fabrication and characterization of photon radiation detectors. The focus has been to develop and improve the performance of optical measurement systems, but also to reduce their cost. The work is based on the study of two types of detectors, the position sensitive detector and the thermal detector. READ MORE

  4. 12. Integration and Packaging Concepts for Infrared Bolometer Arrays

    Author : Adit Decharat; Göran Stemme; Sjoerd Haasl; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fabrication; Bonding; packaging; microbolometer; Thermal imaging.; Other electrical engineering; electronics and photonics; Övrig elektroteknik; elektronik och fotonik;

    Abstract :   Infrared (IR) imaging devices based on energy detection has shown a dramatic development in technology along with an impressive price reduction in recent years. However, for a low-end market as in automotive applications, the present cost of IR cameras is still the main obstacle to broadening their usage. READ MORE

  5. 13. Monte Carlo and Charge Transport Simulation of Pixel Detector Systems

    Author : Jakob Dahlin; Gunnar Skarping; Robert P. Streicher; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; isocyanate; amine; aminoisocyanate; organic acid anhydride; denuder; impactor; impinger; air sampling; LC-MS; LC-CLND; di-n-butylamine; DBA; thermal degradation; aerosol; particles; TDI; MDI; HDI; ICA; MIC; IPDI; exposure; occupational health; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Abstract : This thesis presents methods for air sampling and determination of isocyanates, amines, aminoisocyanates and anhydrides. These organic compounds are generated during thermal degradation of polymers such as polyurethane (PUR) or epoxy.Isocyanates, amines and anhydrides are airway irritants known to cause occupational asthma.

  7. 15. Charge Transport in Single-crystalline CVD Diamond

    Author : Markus Gabrysch; Jan Isberg; Mats Leijon; Milos Nesladek; Uppsala universitet; []
    Keywords : CVD diamond; wide-bandgap semiconductor; single-crystalline diamond; carrier transport; time-of-flight; drift velocity; mobility; compensation; pair-creation; electronic devices; diamond detector; diamond diode;

    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, as compared to other (wide bandgap) semiconductors, make it desirable to develop single-crystalline epitaxial diamond films for electronic device and detector applications.
