    Abstract : Perovskites are a class of compounds with the general formula ABX3 and becoming increasingly attractive recently. Because this kind of material possesses various advantages such as abundant raw materials, easy synthesis, excellent photoelectric properties, and short production process. READ MORE

  5. 3. A First-Principles Study of Highly Anharmonic and Dynamically Disordered Solids

    Author : Johan Klarbring; Sergei Simak; Per Eklund; Claudine Katan; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis is a first-principles theoretical investigation of solid materials with high degrees of anharmonicity. These are systems where the dynamics of the constituent atoms is too complex to be well-described by a set of uncoupled harmonic oscillators. READ MORE
