  1. 11. 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

  3. 12. Single and double clamped resonator sensors - Design, fabrication and testing

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

    Author : Muhammad Islam; [2012]
    Keywords : ;

    Abstract : Micro- and nanomechanical single and double clamped resonators are widely being used as mass and temperature sensors due to their high sensitivity, as bio sensors due to their real time label-free detection ability. These resonators have attracted considerable interest from applications like point of care diagnostics, homeland security and environmental monitoring in recent years. READ MORE

  4. 13. 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

  5. 14. 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
