1. Localized and extended states in finite-sized mosaic Wannier-Stark lattices
University essay from KTH/Tillämpad fysikAbstract : Anderson localization occurs when an otherwise conductive solid becomes insulatingdue to a sufficiently large degree of disorder in the medium. The electron band energy(as a function of disorder) at which this transition between extended and localizedelectron states occur is called the mobility edge (ME) and is energy-dependent only in3-dimensional systems.

2. Radiation Effects on GaN-based HEMTs for RF and Power Electronic Applications
University essay from KTH/Tillämpad fysikAbstract : 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

3. Fabrication of sub-10 nm solid-state nanopores by electrical breakdown
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Nanopore sensing is a versatile technique that employs very small openings, known as nanopores, to study biomolecules. The use of nanopores on solid-state membranes has gained attention due to its potential for low-cost and high-throughput sensing of single molecules in liquids. READ MORE

4. Investigation of Gallium Nitirde High Electron Mobility Transistors
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Gallium Nitride (GaN) based transistors have been in the spotlight for power electronics due to promising properties like high bandgap, high breakdown field, high electron mobility, and high-frequency applications. While there are some commercial devices based on these transistors available, there is still room for improvement in these devices for widespread usage. READ MORE

5. Towards the detection of single photons in the mid-infrared
University essay from KTH/Tillämpad fysikAbstract : In this project, the fabrication of single-photon detectors based on superconducting nanowires is presented, with great focus on extending their operation range to the mid infrared. In particular, Niobium Titanium Nitride (NbTiN) and Molybdenum Silicide (MoSi), superconducting materials with different properties, are presented, studied and used as fabrication platforms. READ MORE
