  1. 1. Theoretical study of anisotropic effects in crystal growth on the example of concrete and calcium oxalate monohydrate

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Vilhelm Ekberg; [2019]
    Nyckelord :anisotropic crystal growth; COM; C-S-H; PM6; ReaxFF$_{ textrm{SiO}}$; organizing molecular matter; nanochemistry; nanokemi; Chemistry;

    Sammanfattning : While many crystals, both natural and artificial, grow isotropically, there are examples of crystals growing anisotropically. The aim of this theoretical study was to confirm the growth modes displayed by three different crystals, representing 3D, 2D and 1D structures. LÄS MER

  3. 2. Crystal Plasticity Finite Element Modelling of Tin Crystals Using Phase Fields

    Kandidat-uppsats, Lunds universitet/Hållfasthetslära

    Författare :Viktor Hultgren; [2018]
    Nyckelord :crystal plasticity; finite deformation; phase field; MOOSE; FEM; Technology and Engineering;

    Sammanfattning : Tin whiskers have long caused issues to electronic components and made the subject of many articles. According to NASA the oldest reports concerning whiskers date back to the 1940's. The whiskers are single-crystals growing from, for example electronic components. LÄS MER

  4. 3. Simulation of cubic GaN growth in SA MOVPE

    Master-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Daniel Nilsson; [2009]
    Nyckelord :simulation; gallium nitride; SAG MOVPE; anisotropic;

    Sammanfattning : In this work growth of cubic GaN in the selective area (SA) MOVPE process is simulated. The simulations are restricted to small pattern SA MOVPE growth. In this case the traditional MOVPE growth and the enhanced growth caused by surface diffusion are important growth factors. LÄS MER
