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. Development of thick GaN and AlGaN drift layers for vertical power devices
University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenAbstract : High-quality, thick III-nitride epitaxial drift layers with controlled doping are needed for next-generation highly efficient vertical power devices for a smart grid applications and electrification of mobility. Achieving desirable material properties, such as low background impurity concentrations and reduced dislocation densities in combination with high growth rates, necessary for practical application present a challenge.

3. Characterization of Bi-incorporated InSb(111)A/B Surfaces : An STM and XPS Study
University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenAbstract : In recent years, III-V semiconductor materials have received increasing attention due to their admirable electronic properties like direct tunable bandgaps and high charge carrier mobility. Indium Antimonide (InSb) possesses the largest electron mobility among III-V materials and is promising for infrared detectors, high-speed field effect transistors, and spintronics. READ MORE

4. Link Adaptation in 5G Networks : Reinforcement Learning Framework based Approach
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Link Adaptation is a core feature introduced in gNodeB (gNB) for Adaptive Modulation and Coding (AMC) scheme in new generation cellular networks. The main purpose of this is to correct the estimated Signal-to-Interference-plus-Noise ratio (SINR) at gNB and select the appropriate Modulation and Coding Scheme (MCS) so the User Equipment (UE) can decode the data successfully.
