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
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 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. LÄS MER
2. Dielectric Response of SiC-based Stress Grading Material Used in Electrical Machines
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : High Voltage (HV) rotating machines are widely used in power generation and heavy industry companies. Silicon Carbide (SiC) material is used in the stress grading structure of HV electric machines because of its non-linear characteristic. LÄS MER
3. Designing a Physical Unclonable Function for Cryptographic Hardware
Master-uppsats, Linköpings universitet/Institutionen för teknik och naturvetenskap; Linköpings universitet/Tekniska fakultetenSammanfattning : Hardware Security Modules (HSMs) are embedded systems that provide a physically secure data storage and handling environment. This master thesis evaluates an HSM method incorporating cryptographic key generation, key management, and tamper protection. LÄS MER
4. Barrier properties of model coatings using recycled iron oxide pigment
Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : The aim of this study was to compare the barrier properties of organic coatings with the same polymer matrix but different types of iron oxide particles, commercial and recycled. The work was carried out for the company SSAB with the aim of investigating whether the pigment Merox ferric oxide, which is produced in-house at the company during the pickling process, can be used and replace commercial iron oxide pigment.

5. Electrical analysis of interface recombination of thin-film CIGS solar cells
Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : In this master thesis, electrical characterization of thin film CuInxGa(1−x)Se2 solar cells produced by Midsummer AB were performed with the aim of determining the dominant recombination path of these cells. Current-Voltage (IV), Quantum Effinciency (QE), temperature dependent IV (IVT) and Drive-Level Capacitance Profiling (DLCP) was used with the objective to investigate the dominant recombination path as well as provide some insight of the solar cells in order to create a baseline model using the modelling software SCAPS (Solar cell CAPacitance Simulator).
