  1. 6. Structure and Thermoelectric Properties of Type-I Clathrates Ba8(AlxGa1−x)16Ge30

    Författare :Yifei Zhang; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microstructure; Crystal structure; Transport properties; Thermoelectrics; Clathrates;

    Sammanfattning : Thermoelectric materials enable the direct conversion between a thermal gradient and an electrical potential gradient, and can thus be exploited for electricity generation. One of the promising thermoelectric materials is type-I clathrates. LÄS MER

  3. 7. Atomic scale modeling of ordering phenomena in inorganic clathrates

    Författare :Mattias Ångqvist; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; ordering phenomena; Cluster expansion; Monte Carlo; Inorganic clathrates;

    Sammanfattning : Ordering phenomena in materials often have a crucial impact on materials properties. They are governed by the competition between entropy and energy. Accordingly simulating these aspects requires the construction of models that enable an computationally efficient exploration of the relevant configuration space. LÄS MER
