1. Interaction and disorder in helical conductors
Abstract : Different effects from electron-electron interactions and disorder in helical and quasi-helical conductors are studied using bosonisation and renormalisation group methods. The combined effects of Rashba spin-orbit interaction and magnetic Kondo-type impurities in the helical edge liquids of quantum spin Hall insulators, are investigated. READ MORE

2. Solid state proton conductors: hydrated perovskites and hydrated alkali thio-hydroxogermanates
Abstract : This thesis concerns experimental studies of hydrated perovskites and hydrated alkali thio-hydroxogermanates, two classes of solid state proton conductors which are promising to be used as electrolytes in future intermediate temperature (200-500°C) fuel cells.This is an attractive temperature range for many applications but for which today's available electrolytes do not show satisfactory performance.

3. Coated Surfaces for Inkjet-Printed Conductors
Abstract : In this thesis, a number of commercially available paper substrates of various types are characterized and their characteristics related to the performance of inkjet-printed conductors using silver nanoparticle ink. The evaluated performance variables are electrical conductivity as well as the minimum achievable conductor width and the edge raggedness. READ MORE

5. Intermediate Temperature Solid Ionic Conductors and Fuel Cells
Abstract : Novel solid proton conductors based on oxyacid salts and salt-ceramic composites and intermediate temperature fuel cells have been developed in this thesis work. The discovery of proton conduction in these materials introduces a new concept of proton conductors and starts a new research field - Intermediate Temperature Solid Proton Conductors and Fuel Cells.
