1. Structural, Electronic and Mechanical Properties of Advanced Functional Materials
Abstract : The search for alternate and renewable energy resources as well as the efficient use of energy and development of such systems that can help to save the energy consumption is needed because of exponential growth in world population, limited conventional fossil fuel resources, and to meet the increasing demand of clean and environment friendly substitutes. Hydrogen being the simplest, most abundant and clean energy carrier has the potential to fulfill some of these requirements provided the development of efficient, safe and durable systems for its production, storage and usage.

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

3. Charge Transport in Transition Metal Oxide Thin Films and Electrochromic Devices
Abstract : Thin film devices for windows, mirrors, space applications and other purposes, have become an essential part of modern technology. A great advantage with a thin film device is the small amount of material used and the compact volume of the device. READ MORE

4. All-Thin-Film Electrochromic Devices for Optical and Thermal Modulation
Abstract : The optical properties of electrochromic materials can be changed by application of an electrical voltage. The conventional electrochromic device consists of several thin films of electrochromic materials and layers for electron- and ion conduction. READ MORE

5. Defect Thermodynamics and Kinetics in Polyanionic Cathodes : A Theoretical Roadmap for Na-ion based Batteries and Hybrid Supercapacitors
Abstract : In this thesis, the framework of the density functional theory is employed to study and predict properties of polyanionic cathodes for Na-ion batteries and hybrid supercapacitors. It consists of three main parts as follows:The first part is primarily dedicated to kröhnkite-type Na2Fe(SO4)22H2O cathode. READ MORE
