  1. 1. 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

  3. 2. Evaluating Security Mechanisms of Substation Automation Systems

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

    Author : Ziyang Zhou; [2023]
    Keywords : Substation automation system; Threat modeling; Meta attack language; Stationsautomationssystem; Hotmodellering; Meta attack language;

    Abstract : Substations are important components for transforming voltage and distributing power in electrical infrastructure. Modern substations are usually automated by substation automation systems, which offload the work of operators and reduce potential human error. READ MORE

  4. 3. In-Situ Investigation of Particle Assisted GaSb Nucleation Using Environmental TEM

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Aidas Urbonavicius; [2023]
    Keywords : ETEM; Nucleation; GaSb; Nanowires; Materials chemistry; Technology and Engineering; Chemistry;

    Abstract : III-V semiconductor material based nanowires have been extensively studied and shown to be a very exciting building block for future electronics. Material systems such as GaSb show a lot of promise in optoelectric and thermoelectric generation applications because of its high electron mobility and small bandgap. READ MORE

  5. 4. Synthesis of Organo-Iron(II) Complexes Including N-Heterocyclic Carbene Ligation as Solar Cell Material.

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Salim Charkas; [2023]
    Keywords : Dye-sensitized solar cell; Transition metal complex; Synthesis iron; N-heterocyclic carbene NHC ; Organic chemistry; Chemistry;

    Abstract : The push-pull design has been shown to increase DSC performance through the introduction of electron-withdrawing groups and electron-donating groups, usually on opposite far ends of the sensitizer. The scope of this thesis was to synthesize several pre-N-heterocyclic carbene ligand analogs that are inspired by the push-pull design in an attempt to investigate their susceptibility to Fe(II) complexation.
