  1. 1. Quantum Transport in Topological Insulator Nanowires

    University essay from KTH/Fysik

    Author : Sergi Pradas Rodriguez; [2023]
    Keywords : quantum transport; topological insulators; nanowires; numerical analysis; Kwant; etc.; kvanttransport; topologiska isolatorer; nanotrådar; numerisk analys; Kvant; etc.;

    Abstract : Three-dimensional topological insulators are materials that have a bulk band gap like a traditional insulator, but which hold topologically protected conducting surface states. In this thesis we present a numerical analysis of the surface states of topological insulator nanowires in the tight-binding approximation. READ MORE

  3. 2. Characterization of Bi-incorporated InSb(111)A/B Surfaces : An STM and XPS Study

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Shengpeng Huang; [2023]
    Keywords : indium antimonide; surface reconstructions; bismuth deposition; scanning tunneling microscopy; X-ray photoelectron spectroscopy.; Physics and Astronomy;

    Abstract : 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. 3. Comparison in Barcode and Computing Time for Persistent Homology Applied to a Subset of a Point Cloud

    University essay from

    Author : André Lasses Armatowski; [2022]
    Keywords : ;

    Abstract : At the intersection of topology and computer science lies the field of topological data analysis(TDA). TDA uses the concept of persistence to identify low dimensional topological features of data embedded in high dimensions. READ MORE

  5. 4. Random Matrix Models

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Evangelos Tsolakidis; [2022]
    Keywords : Random Variables; Matrix Models; Graph Theory; Bootstrap;

    Abstract : In this thesis, we provide a self contained introduction to the theory of random matrices and matrix models. Our analysis has a chronological order and it begins with the study of nuclear energy levels and ensemble averaging which yields the famous Wigner surmise. READ MORE

  6. 5. Application of HEC-HMS modelling on River Storån,Model evaluation and analysis of the processes by using soil moisture accounting loss method

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Pooja Makki Vijayaprakash; [2021]
    Keywords : River Storån; HEC-HMS; SMA; streamflow; baseflow; evapotranspiration; Technology and Engineering;

    Abstract : River Storån, a major tributary of Lake Bolmen which is a source of fresh water to Skåne county of Sweden is found to alter the color of water in the lake due to the presence of natural organic matter. Hence it is of utmost importance to study the river to understand the dynamics of generation and flow of water from the river to the lake. READ MORE
