  1. 1. Automated noise measurements for very long wavelength infrared detectors

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : David Ramos Santesmases; [2019]
    Keywords : Noise; Infrared detector; QWIP; T2SL; Brus; Infraröd detektor; QWIP; T2SL;

    Abstract : The potential imaging performance of infrared (IR) detectors is dependent on the noise level in the detector pixels. Noise measurements at pixel level can therefore provide basic understanding of the intrinsic limitations of detectors. READ MORE

  3. 2. Characterization of single InP Nanowire-based Avalanche Photodetectors

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Author : Virginia Boix De La Cruz; [2016]
    Keywords : Photodetectors; Nanotechnology; Nanowires; IndiumPhosphide; Semiconductors; Physics and Astronomy;

    Abstract : Nanoscience is an emerging field of technology where the bottom-up fabrication techniques are utilized instead of the traditional top-down approaches for enhancing the performance of di erent optoelectronic devices. One such material is a semicon- ductor nanowire (NW) which holds immense potential in nanophotonic applications, such as solar cells, LEDs, lasers, sensors and photodetectors. READ MORE

  4. 3. Antireflection Patterning of Si for InAsSb Nanowire Infrared Photodetectors

    University essay from Lunds universitet/Fysiska institutionen

    Author : Muhammad Rizwan Khalid; [2014]
    Keywords : Physics and Astronomy;

    Abstract : The pattering of an optical surface with physical features like with very low reflectivity and high transmission of IR or visible light can be used e.g. for antireflective windows for solar cells and photodetectors. READ MORE

  5. 4. Electrical and optical characterization of InP nanowire-based photodetectors

    University essay from Högskolan i Halmstad/Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Author : Jiang Dawei; [2014]
    Keywords : IR photodetectors; electrical characteristics; optical characteristics; nanophotonics; InP; nanowires.;

    Abstract : This thesis deals with electrical and optical characterization  of p+i–n+ nanowire-based photodetectors/solar  cells. I have investigated their I-V performance and found that all of them exhibit a clear rectifying behavior with an ideality factor around 2.2 at 300K. READ MORE

  6. 5. Characterization of InSb quantum dots in InAs matrix grown by molecular beam epitaxy for infrared photodetectors

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

    Author : Laiq§ Hussain; [2011]
    Keywords : ;

    Abstract : Materials for the generation and detection of long wavelength IR radiation continue to be of considerable interest for many applications such as night vision, defense and security, rescue, life sciences, industrial processing etc. For this purpose photodetection based on InSb is a well known technology in mid wavelength (3-5 μm) range.
