  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

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

    Author : Ivan Krsic; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 2. Klimatutsläpp från Region Uppsalas solcellsanläggningar ur ett livscykelperspektiv

    University essay from SLU/Dept. of Energy and Technology

    Author : Bianca Nilsson; [2023]
    Keywords : livscykelanalys; energiplanering; solceller; jämförelse av solcellstekniker; klimatutsläpp; solcellspark;

    Abstract : Solceller är en del av en ny teknik för att kunna producera förnyelsebar energi som kan ersätta dagens fossila energikällor. Syftet med denna studie är att undersöka hur stora klimatutsläppen blir för de olika solcellsanläggningarna i Region Uppsala ur ett livscykelperspektiv, samt vilka faktorer som påverkar utsläppen.

  5. 4. Synchrotrons as a Source for Soft X-Ray Lithography

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Thomas Joseph Grandsaert Jr; [2021]
    Keywords : Physics and Astronomy;

    Abstract : To move to lower modes in extreme ultra-violet lithography (EUVL) technology (and keep up with Moore’s law), new sources of soft X-ray radiation must be developed. It is clear from previous studies that Free Electron Lasers (FELs) can easily meet the in-band power requirements at these lower wavelength modes, however detailed studies for insertion devices (undulators) as a soft X-ray lithography (SXL) source are due for a re-evaluation.

  6. 5. Work function engineering for high temperature FD-SOI transistors

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

    Author : Chenxi Wang; [2021]
    Keywords : ;

    Abstract : Various applications require the MOSFETs that work at a high temperature which is ambient operating temperature higher than 125 ℃. However, the traditional bulk MOSFETs at high temperature suffers from high leakage currents and threshold voltage shift, thus the performance of the bulk MOSFETs is severely degraded. READ MORE
