  1. 1. Establishing High-Temperature Models for Leakage Current in Gated Lateral Bipolar Junction Transistors

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Jimmy Atterstig; [2024]
    Keywords : Electronics; leakage current; brokaw bandgap; semiconductor physics; gauss-newton;

    Abstract : Power-efficient circuits are a vital step in moving towards a greener future. Battery life can get substantially improved by decreasing the amount of power a circuit needs. Lower power also leads to less excess heat generated. READ MORE

  3. 2. 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

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

    Author : Agnimitra Saha; [2023]
    Keywords : Silicon Carbide; Gate Bias Stress; Threshold Voltage; On-state Resistance; Temperature; kiselkarbid; gate spännings-stress; tröskelspänning; on-resistansen; temperatur;

    Abstract : 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. READ MORE

  4. 3. Framing Russia in the National Security Strategy of the United States of America

    University essay from Uppsala universitet/Institutet för Rysslands- och Eurasienstudier; Uppsala universitet/Institutionen för informatik och media

    Author : Elvira Sitkevica; [2023]
    Keywords : USA; Russian Federation; National Security Strategy; international politics; international relationships; framing analysis; qualitative study; social constructivism;

    Abstract : Historically, the USA and Russian Federation have been two world powers that used to compete for a dominant power position in the bipolar world and spread influence on less developed countries. Relationships between the USA and Russia have mostly been complex and tense,with several escalation periods during the Cold War. READ MORE

  5. 4. Investigation of charge injection at electrode-dielectric interface relevant for HVDC cables : Simulation of charge injection and transport dynamics in electrical insulation for HVDC cables

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Mohammed Mosa; [2023]
    Keywords : BCT model; charge injection; space charge density; electric field distribution; Fowler-Nordheim; Richardson-Schottky;

    Abstract : A bipolar charge transport (BCT) model is used to simulate charge injection and transportdynamics inside insulation material which are used in a high voltage direct current (HVDC)cable. Gaining knowledge about space charge density and electric field distribution in theinsulation material enables minimising charge injection at the metal-insulator interface andavoiding unnecessary energy loss.

  6. 5. The Making of "White Spaces" : The construction, disruption, and maintenance of stability in bipolar realities in Sweden

    University essay from Stockholms universitet/Socialantropologiska institutionen

    Author : Emma Larsen; [2023]
    Keywords : Medical anthropology; mental illness; bipolar disorder; treatment; mental health; anthropology of becoming; knowledge production; knowledge sharing; agency; power; knowledge-power; social anthropology; cultural anthropology;

    Abstract : Bipolar disorder is a condition rarely approached in anthropological research, and even less so through the eyes of people living with the disorder. Therefore, to focus on understanding the experience of the state in-between episodes, here referred to as a “white space”, is rare and in need of further examination. READ MORE
