A Three-Dimensional Finite Element Poisson Solver for Monte Carlo Particle Simulators
Fatnes, Siri Narvestad (Master thesis, 2018)A finite element Poisson solver for the calculation of the three-dimensional electric field in self-consistent particle simulations has been implemented in Fortran and integrated into an existing Monte Carlo simulator for ... -
Calculation of Wavefunction Overlaps in First Principles Electronic Structure Codes
Goldar, Dara (Master thesis, 2017)In the work with this Master thesis, expressions for the wavefunction overlap factor between eigenfunctions are obtained. These expressions should be suitable for numeric integration over the Brillouin zone, and are derived ... -
Carrier Scattering Rates in Zincblende Structure Semiconductors derived from 14 × 14 k · p and ab initio Pseudopotential Methods
Karlsen, Bjørnar (Master thesis, 2013)A set of programs for calculating carrier-phonon and carrier-alloy scat-tering rates have been constructed. Energy bands, gradients of the energy, second derivatives of the energy and eigenvectors of the carrier states ... -
Development of a 3D Particle-Based Device Simulator: A Self-Consistent Monte Carlo Approach Using Tetrahedral Grids
Bolstad, Andreas (Master thesis, 2020)Essensielt for optimering av halvlederkomponenter er å kunne simulere dem med realistiske geometri- og material-egenskaper. Et nytt simuleringsprogram presenteres som kombinerer en partikkelbasert simuleringsmetode med ... -

InAsSb/AlInAsSb nBn Photodiodes - A Basic Device Model
Marín Aguilera, Guillem (Master thesis, 2021)I dette arbeidet er bandstrukturen til en Unipolar Barrier Infrared Detector simulert. Designforslaget for sensoren er basert på en tidligere studie utført av forfatteren. Komponenten består av en heterostruktur som ... -
Schrödinger-Poisson and nonequilibrium Green's function methods applied to layered semiconductor devices
Haug, Mikael (Master thesis, 2018)In this work, electron transport through layered semiconductor heterostructure devices in the nanometer dimension are simulated. Because these devices have shrunk in the last decades, it is no longer sufficient to utilize ... -
Simulation of infrared avalanche photodiodes from first principles
Storebø, Asta Katrine; Goldar, Dara; Brudevoll, Trond (Journal article; Peer reviewed, 2017)The present article deals with device physics and modeling of an Hg0.28Cd0.72Te wide-area electron-initiated avalanche photodiode, with main input data extracted from first principles electronic structure codes. Due to the ... -
Study of a Triangular-Domain Topological Qubit Model with Edge disorder
Høye, Osmund (Master thesis, 2022)Topologi for faste stoffer er et eksotisk felt som kan få viktige implikasjoner for kvanteberegninger. Måten nåværende kvantedatamaskiner implementeres fysisk lider av korte koherenstider og medførende høye feilrater. ... -
The Isotropic Hyperfine Interaction in Silicon Quantum Dots
Johansen, Solfrid Hagen (Master thesis, 2021)Kvantedatamaskiner kan i teorien utføre visse beregninger som ikke er mulig å utføre på klassiske datamaskiner. En begrensende faktor for bruk av kvantedatamaskiner er dekoherensetiden til en kvantebit (qubit), da dette ... -
Utregning av det elektromagnetiske feltet i Monte Carlo transport simulering
Harang, Jonas Julius (Master thesis, 2017)Løsning av poissons ligning under monte carlo simulering av en CdHgTe fotoskred-diode. Vi har tatt i bruk ikke-uniform mesh med adaptivt grid og gjort noen elementære simuleringer av CMT dioden.
