  1. 1. Off-State Stress Effects in AlGaN/GaN HEMTs : Investigation of high-voltage off-state stress impact on performance of and its retention in hybrid-drain ohmic gate AlGaN/GaN HEMTs

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

    Författare :Ivan Krsic; [2023]
    Nyckelord :HEMT; GaN; off-state stress; memory effects; drain leakage current; dynamic RDSon; threshold voltage instabilities; charge redistribution; HEMT; GaN; stress i avslaget tillstånd; minneseffekter; läckströmmen; dynamisk RDSon; instabiliteten hos styrets tröskelspänning; omfördelningen av laddningar;

    Sammanfattning : High electron mobility transistors (HEMTs) realized using AlxGa1-xN/GaN are relatively new technology which is prominent for high-speed and high-power applications. Some of the main problems with this technology were identified as dynamic RDSon, current collapse and threshold voltage instabilities due to the off-state stress. LÄS MER

  3. 2. Resurseffektivisering i värdekedjan inomproduktion med hjälp av dataöverföring

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Douglas Danfors; Kasper Back; [2023]
    Nyckelord :;

    Sammanfattning : Industriell produktion har bedrivits ända sen den industriella revolutionen tog fart under 1800-talet och har fram till idag genomgått flera stora förändringar. Med de stora problem vi idag ser i form av klimatförändringar som måste bromsas så krävs det att hela samhället och inte allra minst industrier resurseffektiviseras. LÄS MER

    Sammanfattning : Deep Learning models have seen great application in demanding tasks such as machine translation and autonomous driving. However, building such models has proved challenging, both from a computational perspective and due to the requirement of a plethora of annotated data. LÄS MER

  7. 5. High Precision Robotic Manipulator for Bluelining at MAX IV

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Vinay Venkanagoud Patil; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : MAX IV is a synchrotron facility currently running 14 beamlines hosting about 1000 users per year. It is one of the best of its kind; producing high quality Xrays at the forefront of synchrotron science. To have a beamline or a synchrotron functional, every equipment used needs to be placed in the workspace with high precision. LÄS MER
