  1. 1. The STM Study of Bi Adsorption on the InAs(111)B Surface

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

    Author : Jung-Ching Liu; [2019]
    Keywords : bismuth; indium arsenide 111 B; adsorption; surface; scanning tunneling microscopy; Physics and Astronomy;

    Abstract : Semiconductors composed of group III and group V elements have a variety of promising applications, such as topological insulators and quantum computers. Among this category of semiconductors, bismuth (Bi)-containing III-V compounds are able to make these applications possible. READ MORE

  2. 2. Band structures of topological crystalline insulators

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik

    Author : Elisabet Edvardsson; [2018]
    Keywords : Topological insulator; Band structure; Block tridiagonal matrix;

    Abstract : Topological insulators and topological crystalline insulators are materials that have a bulk band structure that is gapped, but that also have toplogically protected non-gapped surface states. This implies that the bulk is insulating, but that the material can conduct electricity on some of its surfaces. READ MORE

  3. 3. Axion Electrodynamics and Measurable Effects in Topological Insulators

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Andreas Asker; [2018]
    Keywords : Topological Insulators; Axion Electrodynamics; Topological Magnetoelectric Effect; Topological Field Theory; Faraday-Kerr Effect; Topologiska Isolatorer; Axion Elektrodynamik; Topologiska Magnetoelektriska Effekten; Topologisk Fältteori; Faraday-Kerr Effekten;

    Abstract : Topological insulators are materials with their electronic band structure in bulk resembling that of an ordinary insulator, but the surface states are metallic. These surface states are topologically protected, meaning that they are robust against impurities. READ MORE

  4. 4. An approach of using Delaunay refinement to mesh continuous height fields

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC); KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Noah Tell; Anton Thun; [2017]
    Keywords : Delaunay; height field; height map; chunks; procedural terrain generation; topological surface;

    Abstract : Delaunay refinement is a mesh triangulation method with the goal of generating well-shaped triangles to obtain a valid Delaunay triangulation. In this thesis, an approach of using this method for meshing continuous height field terrains is presented using Perlin noise as the height field. READ MORE

  5. 5. Case Studies on Fractal and Topological Analyses of Geographic Features Regarding Scale Issues

    University essay from Högskolan i Gävle/Samhällsbyggnad, GIS

    Author : Zheng Ren; [2017]
    Keywords : scale; fractal geometry; big data; topological analyses;

    Abstract : Scale is an essential notion in geography and geographic information science (GIScience). However, the complex concepts of scale and traditional Euclidean geometric thinking have created tremendous confusion and uncertainty. READ MORE
