  1. 1. Continuous Integration for Embedded Software with Modular Firmware Architecture

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

    Författare :Fabian Segatz; [2023]
    Nyckelord :Continuous integration; Embedded software development; Modular firmware architecture; Jenkins; Software quality; Kontinuerlig integration; Inbyggd programvaruutveckling; Modulär fastvara arkitektur; Jenkins; Programvarukvalitet;

    Sammanfattning : Continuous Integration (CI) techniques are widely adopted in web and application development but have received limited attention in the embedded software domain. This thesis investigates the application of CI techniques in embedded software development through a case study at Cobolt AB, a company specializing in optoelectronics. LÄS MER

  3. 2. Competing phases of matter: Experimental spectroscopy study of the transition metal dichalcogenides Fe-doped TaS2 and Cu-intercalated TiSe2

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Christian Stefan Gruber; [2023]
    Nyckelord :Condensed matter physics; transition metal dichalcogenides; photoemission spectroscopy;

    Sammanfattning : Syftet med denna avhandling är att bidra till forskningen av befintliga TMD:er (på Engelska transition metal dichalcogenide-TMD) som visar laddningstäthetsvågor och supraledning vid låga temperaturer (som 2H-TaS2). 2H-TaS2 är också känt för att visa supraledning vid 2K.

  4. 3. Mätutrustning för Solcellers Responstid : En Undersökning i Analog Elektronik

    Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Vilgot Samuelsson; Axel Algeroth von Thiele; [2023]
    Nyckelord :elektronik; analog; mätinstrument; solceller; responstid; perovskit; transimpedans; arduino; platformIO; optoelektronik; kretskort;

    Sammanfattning : Perovskite solar cells (PSCs) have shown great potential for the future of solar powered energy production. They are however not completely flawless, and one of their more disadvantageous properties are their relatively slow response time. LÄS MER

  5. 4. Optical characterisation of AAO/CsPbBr3 perovskite nanocomposites

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Klára Nováková; [2021]
    Nyckelord :perovskite; scintillator; optoelectronics; semiconductor; X-ray detection; Physics and Astronomy;

    Sammanfattning : Direct bandgap metal lead halide perovskites offer promising optoelectronic properties desirable in a wide range of applications including photodetection. However, the incomplete and poor understanding of the photophysical processes taking place in these materials, along with their poor stability, is the bottleneck for optimisation and further development of metal halide perovskite devices.

  7. 5. Characterizing optical and electrical properties of monolayer MoS2 by backside absorbing layer microscopy

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Nathan Ullberg; [2020]
    Nyckelord :backside absorbing layer microscopy; BALM; monolayer MoS2; TMD; TMDC; 2D materials; nanomaterials; nanotechnology; refractive index; extinction coefficient; absorption coefficient; field-effect transistor; FET; semiconductors; optoelectronics; optics; raw image processing; chemical vapor deposition; CVD; in situ characterization;

    Sammanfattning : Nanomaterials are playing an increasing role in novel technologies, and it is important to develop optical methods to characterize them in situ.  To that end, backside absorbing layer microscopy (BALM) has emerged as a powerful tool, being capable to resolve sub-nanometer height profiles, with video-rate acquisition speeds and a suitable geometry to couple live experiments.
