  1. 6. Diffractive Optical Elements: Fabrication, Replication, and Applications and Optical Properties of a Visual Field Test

    Author : Fredrik Nikolajeff; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; perimetry; beam homogenizing; antireflection; high-pass spatial frequency target; proximity effect; electron beam lithography; replication; successive development; diffractive optical element; axicon;

    Abstract : This thesis mainly treats the fabrication, replication and applications of diffractive optical elements. A smaller part deals with optical properties of a visual field test. Diffractive optical elements are computer-generated micro-optic components that use diffraction to manipulate light. READ MORE

  2. 7. Graphene spin circuits and spin-orbit phenomena in van der Waals heterostructures with topological insulators

    Author : Dmitrii Khokhriakov; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Graphene; Spin-charge conversion; Topological insulator; Spintronics; Proximity effect; Van der Waals heterostructures;

    Abstract : Spintronics offers an alternative approach to conventional charge-based information processing by using the electron spin for next-generation non-volatile memory and logic technologies. To realize such technologies, it is necessary to develop spin-polarized current sources, spin interconnects, charge-to-spin conversion processes, and gate-tunable spintronic functionalities.

  3. 8. Charge-Spin Conversion and Electronic Transport in Two-Dimensional Materials and van der Waals Heterostructures

    Author : Anamul Md Hoque; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Spin-orbit coupling; Nanoribbons; Nanotransistor; Graphene; Chemical vapor deposition; Spintronics; Charge-spin conversion; Two-dimensional materials; Proximity effect; van der Waals heterostructure;

    Abstract : Applications related to artificial intelligence (AI), 5G communication, cloud computing, Internet of Things (IoT) will necessitate wide range of data collection, communication and processing. Current charge-based technology using conventional materials suffers adverse effects with down-scaling the device size and has limited efficiency in meeting the future demands for computation and data storage.

  4. 9. Managing Distance : Small Firm Networks at the Geographic Margins

    Author : Alexandre Dubois; Brita Hermelin; Andrew Copus; Dimitris Skuras; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; globalisation; periphery; small firms; embeddedness; extralocal networks; proximity; kulturgeografi; Human Geography;

    Abstract : Small businesses located in the most sparsely populated and peripheral parts of Europe are frequently believed to be marginalised with respect to the processes of economic globalisation. This thesis proposes to explore an alternative perspective for understanding how small businesses that are located at the geographical margins engage with the globalised economy. READ MORE

  5. 10. Accessibility to bank branches and entrepreneurial dynamics : New firm formation and capital structure of SMEs in Sweden amidst a changing banking landscape

    Author : Cynthia Sin Tian Ho; Björn Berggren; Jonas Gabrielsson; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; New firm formation; entrepreneurship; capital structure; leverage; financing; bank branches; proximity; spatial analysis; Sweden; Startup; entreprenörskap; kapitalstruktur; finansiering; bankkontor; närhet; spatialanalys; Sverige; Business Studies; Företagsekonomi;

    Abstract : The overall objective of this thesis is to develop a better understanding of the impact of accessibility to bank branches on new firm formation and on the capital structure of small and medium-sized enterprises (SMEs) in Sweden. In this thesis, the accessibility to bank branches is measured by two proxies that are weighted by two different types of population—the labour population and the firm population. READ MORE
