  2. 1. Charge Density Waves and Alkali Metal Intercalation in Layered Materials

    Author : Inger Ekvall; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; charge density waves; STM STS; W tips; alkali metal intercalation;

    Abstract : In this thesis the following issues are discussed: 1. Fundamental properties of two polytypes of TaS2 studied by scanning tunneling microscopy (STM) and spectroscopy (STS). 2. The influence of Na intercalation on charge density waves (CDW's) in 1T-VSe2 and 4Hb-TaS2 studied by STM and STS. READ MORE

  4. 2. Alkali Metal Stripping and Plating in Liquid Electrolytes

    Author : Josef Rizell; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Highly Concentrated Electrolytes; Stripping; Lithium; Potassium; Nucleation; Plating; Metal anodes;

    Abstract : Batteries have relatively modest energy densities compared to fossil fuels. In the efforts to make battery-driven transport solutions and technologies competitive with gasoline-powered alternatives, it is important to develop batteries with higher energy densities. READ MORE

  5. 3. Alkali Metal Aurivillius Phases Structure and Electrical Properties

    Author : Stefan Borg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; neutron powder diffraction; phase transition; X-ray powder diffraction; Aurivillius phases; impedance spectroscopy; Curie temperature; electron microscopy;

    Abstract : The quest for new materials is crucial for the development of smaller and more efficient electronic components. Aurivillius phases have recently received considerable attention due to their wide-ranging properties and are considered promising candidates in e.g. memory devices, microwave filters and fuel cells.

  7. 5. Theoretical Studies on Electronic Structure, Spectra and Conductivity of Pristine and Alkali Doped Polyacetylene

    Author : Lucía Mercedes Rodrigues Monge; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; theoretical calculations; electron transfer; conductivity; polyacetylene; alkali metal; ab-initio methods; charge transport; semiempirical methods; doping;

    Abstract : The present thesis is a theoretical investigation of the electronic properties of linear polyenes to get an insight into conductive phenomena in pristine and doped polyacetylene. Conductivity in polyacetylene is a complex phenomena and cannot be treated within simple band models. READ MORE
