  1. 1. Development and study of luminescent bolometers for neutrino physics

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Yann Gimbal-Zofka; [2017]
    Keywords : Neutrinoless double beta decay; bolometer; scintillating bolometer; leptogenesis; neutrino; cryostat; radioactivity;

    Abstract : This Master thesis aims at designing, assembling and operating a prototypal luminescentbolometer containing a candidate with high Q-value (116Cd and 100Mo)for the study of the neutrinoless double- decay. The crystal is scintillating (with 116CdWO4 and Li2MoO4 compounds). READ MORE

  3. 2. NiSi(C) Schottky diodes for IR detection

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Mahdi Moeen; [2012]
    Keywords : ;

    Abstract : Un-cooled bolometer arrays have been considered as good choices for detection of infrared waves in the ranges of 3-5μm (MWIR: mid wavelength infrared) and 8-12μm (LWIR: long wavelength infrared). Advantages are found in their relative simplicity of mechanism and design, hence, fabrication cost, when compared to detectors working based on photon detection mechanisms. READ MORE

  4. 3. Simulation of Temperature Distribution in IR Camera Chip

    University essay from Informationskodning

    Author : Stefan Salomonsson; [2011]
    Keywords : Thermal modeling; Thermal imaging; Bolometer detector; Finite Element Method; COMSOL Multiphysics;

    Abstract : The thesis investigates the temperature distribution in the chip of an infrared camera caused by its read out integrated circuit. The heat from the read out circuits can cause distortions to the thermal image. READ MORE

  5. 4. Growth and characterization of Ge quantum dots on SiGe-based multilayer structures

    University essay from Institutionen för fysik, kemi och biologi

    Author : Andreas Frisk; [2009]
    Keywords : Ge dots; SiGe; Thermistor; IR-detector; Bolometer; intermixing; strain;

    Abstract : Thermistor material can be used to fabricate un-cooled IR detectors their figure of merit is the Temperature Coefficient of Resistance (TCR). Ge dots in Si can act as a thermistor material and they have a theoretical TCR higher than for SiGe layers but they suffer from intermixing of Si into the Ge dots. READ MORE

  6. 5. Structural and optical characterization of Si/Ge quantum dots

    University essay from Institutionen för fysik, kemi och biologi

    Author : Dan Wigblad; [2008]
    Keywords : quantum dot; IR detector; bolometer; semiconductor; germanium; silicon;

    Abstract : In this study silicon-germanium quantum dots grown on silicon have been investigated. The aim of the work was to find quantum dots suitable for use as a thermistor material. The quantum dots were produced at KTH, Stockholm, using a RPCVD reactor that is designed for industrial production. READ MORE
