  1. 6. Characterisation of GaN HEMTs on Different Substrates for Power Electronics Applications

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

    Author : Hithiksha Krishna Murthy; [2022]
    Keywords : Gallium nitrate; High Mobility Electron Transistor; Silicon carbide; Silicon; Sapphire; substrates; power electronics;

    Abstract : GaN-based High Electron Mobility Transistors (HEMT) are appealing because of their large breakdown field, high saturation velocity, and superior thermal conductivity. They work at high temperature without much degradation. HEMTs have a few drawbacks despite many positives. The cost of developing GaN HEMTs on a native substrate is high. READ MORE

  3. 7. Numerical Simulation of 3.3 kV–10 kV Silicon Carbide Super Junction-MOSFETs for High Power Electronic Applications

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

    Author : Rishi Balasubramanian Saraswathy; [2022]
    Keywords : Super–Junction; DMOSFET; 4H-SiC; Silicon Carbide; Wide bandgap; 6.5 kV; 10 kV; On-state resistance; Breakdown voltage; Super–Junction; DMOSFET; 4H-SiC; kiselkarbid; bredbandgap; 6.5 kV; 10 kV; framspänningsfall; spärrspänning;

    Abstract : The thesis focuses on designing and characterizing SiC 3.3 kV Diffused Metal-Oxide Semiconductor Field-Effect Transistor (DMOSFET)s with a Ron that is significantly lower than that of current commercial devices. The On-state resistance and breakdown voltage are then adjusted by adding a Super-Junction structure. READ MORE

  4. 8. Navigating the politics of transformative change towards sustainability: A case study of Extinction Rebellion’s climate crisis framing

    University essay from Stockholms universitet/Stockholm Resilience Centre

    Author : Hannes Eggert; [2021]
    Keywords : Extinction Rebellion; social movements; framing; climate change; de- politicization; transformation;

    Abstract : Research on transformations has recognized that trajectories towards sustainability are negotiated and contested through framings and narratives. There is, however, still a greater need to explore the role of social movements and their ability to characterize a problem, propose solutions and motivate the public to become engaged. READ MORE

  5. 9. Investigation of Gallium Nitirde High Electron Mobility Transistors

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

    Author : Shikhar Arvind; [2021]
    Keywords : Gallium Nitride; High electron mobility transistor; leakage current; in-situ Silicon Nitride; power electronics;

    Abstract : Gallium Nitride (GaN) based transistors have been in the spotlight for power electronics due to promising properties like high bandgap, high breakdown field, high electron mobility, and high-frequency applications. While there are some commercial devices based on these transistors available, there is still room for improvement in these devices for widespread usage. READ MORE

  6. 10. Design of an Incubator Platform for Biological ISS Experiments

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Anne Sophie Hartmann; [2021]
    Keywords : ICE Cubes; BioCube; SpaceMaster; ISS; Space System Engineering; Space Applications Service; Space Experiment; Rapid Prototyping;

    Abstract : The first European commercial research facility aboard the ISS, Space Applications Services' ICF, provides a platform for standardized plug-and-play experiments called ICE Cubes. The ICE Cubes Service provides engineering and operational support for ICE Cubes missions. READ MORE
