  3. 2. Automated noise measurements for very long wavelength infrared detectors

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Sammanfattning : 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. LÄS MER

  4. 3. Studies on Radiation-induced Defects in InP/InAsP Nanowire-based Quantum Disc-in wire Photodetectors

    Magister-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Nyckelord :InP InAsP; QDiscs-in-wire; photodetectors; proton irradiation; Photocurrent; I-V characteristics;

    Sammanfattning : Photodetectors are used in many applications such as digital and thermal cameras or in solar panels. They can also be designed to detect the omnipresent high-energy radiation/particles, and for radiation imaging in biomedical applications. LÄS MER

  5. 4. Stacked Dual Narrowband Organic Near-Infrared Photodetectors

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Yazhong Wang; [2017]
    Nyckelord :Near-infrared; photodetectors; CT states; Fabry-Perot resonant cavity; resonant cavity enhancement; tunability; full width at half maximum;

    Sammanfattning : Compared with the detector devices made of inorganic semiconductors, organic photodetectors are granted with additional strengths, such as flexibility, high scalability and bio-compatibility. However, in the family of organic optoelectronic devices, the detectors that are capable of detecting photons at two or multiple specific wavelengths are still missing. LÄS MER

  7. 5. Characterization of single InP Nanowire-based Avalanche Photodetectors

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

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

    Sammanfattning : 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. LÄS MER
