  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

    Sammanfattning : Sammanfattning Bakgrund Fastighetsmäklaryrket är en ständigt växande bransch med hög rörlighet och där allt fler individer väljer att utbilda och registrera sig till fastighetsmäklare varje år. Det finns även en relativt hög andel som väljer att lämna yrket inom kort tid efter registrering. LÄS MER

  4. 3. Customizable Contraction Hierarchies for Mixed Fleet Vehicle Routing : Fast weight customization when not adhering to triangle inequality

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

    Författare :Martin Larsson; [2023]
    Nyckelord :Contraction Hierarchies; Customizable Contraction Hierarchies; Vehicle Routing Problem; Battery Electric Vehicles; Mixed Fleet; Kontraktionshierarkier; Anpassningsbara Kontraktionshierarkier; Ruttplanering; Batteridrivna elfordon; Blandad fordonsflotta;

    Sammanfattning : As the transport industry shifts towards Battery Electric Vehicles (BEVs) the need for accurate route planning rises. BEVs have reduced range compared to traditional fuel based vehicles, and the range can vary greatly depending on ambient conditions and vehicle load. LÄS MER

  5. 4. AC Gate Bias Stress of 4H-SiC MOSFETs : An investigation into threshold voltage instability of SiC Power MOSFETs under the influence of bipolar gate stress

    Sammanfattning : Silicon Carbide, a wide band gap (WBG) semiconductor, has pushed electrical limits beyond Silicon (Si) when it comes to power electronics. It has offered the electrification of society showing promise for a greener future. LÄS MER

  7. 5. To Activate, Expose and Elicit thinking : a three step journey Teacher actions and student thinking in 18 Swedish mathematics classrooms in upper secondary

    Master-uppsats, KTH/Lärande

    Författare :Carina Bark; [2023]
    Nyckelord :mathematical thinking; classroom observations; thinking progression; higher order thinking skills; HOTS; mathematics education; upper secondary; matematiskt tänkande; klassrumsobservationer; högre ordningens tänkande; tänkande-progression; HOTS; matematikundervisning; gymnasium;

    Sammanfattning : Today’s research, as well as current Swedish governance documents, stress the high importance of developing students’ abstract, individual and critical thinking in mathematics education. The needs for such quality thinking however stand in stark contrast to the ‘traditional mathematics education’, which cannot be expected to develop such thinking. LÄS MER
