  1. 1. Radiation Effects on GaN-based HEMTs for RF and Power Electronic Applications

    University essay from KTH/Tillämpad fysik

    Author : Wilhelm Holmberg; [2023]
    Keywords : High Electron Mobility Transistor; HEMT; Gallium Nitride; GaN; Silicon Carbide; SiC; Proton Radiation; Galliumnitrid; GaN; Kiselkarbid; SiC; Kisel; Si; HEMT; Transistor; Protonstrålning;

    Abstract : GaN-HEMTs (Gallium Nitride-based High Electron Mobility Transistors) have, thanks to the large band gap of GaN, electrical properties that are suitable for applications of high electrical voltages, high currents, and fast switching. The large band gap also gives GaN-HEMTs a high resistance to radiation. READ MORE

  2. 2. (1,3-di-tert-butyltriazenide) Cu(I) as vapor deposition precursor

    University essay from Linköpings universitet/Kemi

    Author : Peggy Bagherzadeh; [2023]
    Keywords : Vapor deposition; CVD; ALD; triazenide;

    Abstract : In the past few decades, devices such as computers have become smaller, and their performance has improved beyond comparison. Semiconductors and interconnectors are used in almost all devices today and are made of thin films. READ MORE

  3. 3. Odlingsförsök med Pinus sylvestris i gransågspån blandat med hydrokol respektive pyrokol

    University essay from SLU/School for Forest Management

    Author : Annica Berglund; Ninja Bernzen; [2023]
    Keywords : alternativt odlingssubstrat; näringsläckage; biokol;

    Abstract : Torv är det vanligaste odlingssubstratet som används idag till de mer än 400 miljoner skogsplantor som årligen levereras till det svenska skogsbruket. Det låga näringsinnehållet och goda vattenhållande förmågan gör att torven går att anpassa efter behov med gödsling och kalkning. READ MORE

  4. 4. Fabrication and characterization of GaAsxP1-x single junction solar cell on Si for III-V/Si tandem solar cell

    University essay from KTH/Tillämpad fysik

    Author : Elaheh Aghajafari; [2023]
    Keywords : III-V semiconductor; GaAsxP1-x heteroeputaxy; hydride vapor phase epitaxy; III-V Si solar cell; III-V halvledare; GaAsxP1-x epitaxiallager; hydridångfasepitaxi; III-V Si solcell;

    Abstract : Silicon based solar cells have been used as photovoltaic devices for decades due to reasonable cost and environment- friendly nature of silicon. But the conversion efficiency of silicon solar cell is limited; for instance, the maximum conversion efficiency of a crystalline silicon solar cell available in the market developed by Kaneka Corporation is 26 % [1].

  5. 5. Assessment of oyster mushroom production employing urban-based materials in Stockholm Stad

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Mio Fagerström; [2023]
    Keywords : Industrial symbiosis; residual waste streams; Pleurotus ostreatus; Oyster mushroom cultivation; Circular economy; Industriell symbios; restavfallsströmmar; Pleurotus Ostreatus; Ostronskivlings odling; cirkulär ekonomi;

    Abstract : This thesis investigates the opportunities and challenges regarding urban oyster mushroomproduction (Pleurotus Ostreatus) employing urban-based materials in Stockholm Stad as agrowing medium. Additionally, the availability of the five most suitable substrates has beenfurther explored with the indicator’s availability in Stockholm Stad, and the Biologicalefficiency (BE%) for a suitable growing medium and the quantity of the substrates have beenmapped out.
