1. Charge Transport in Single-crystalline CVD Diamond
Abstract : Diamond is a semiconductor with many superior material properties such as high breakdown field, high saturation velocity, high carrier mobilities and the highest thermal conductivity of all materials. These extreme properties, as compared to other (wide bandgap) semiconductors, make it desirable to develop single-crystalline epitaxial diamond films for electronic device and detector applications.

2. Flocculation with Polyelectrolytes in Latex and Microbial Systems
Abstract : Adsorption of cationic polyelectrolytes onto polystyrene latices was studied as function of polymer chemical composition and molecular weight, polymer and surface charge density and ionic strength. The ratio between polymer charges and surface charges was close to one when distances between polymer and surface charges were equal. READ MORE

3. Experimental Studies of Charge Transport in Single Crystal Diamond Devices
Abstract : Diamond is a promising material for high-power, high-frequency and high- temperature electronics applications, where its outstanding physical properties can be fully exploited. It exhibits an extremely high bandgap, very high carrier mobilities, high breakdown field strength, and the highest thermal conductivity of any wide bandgap material. READ MORE

5. Molecular machinery of a membrane-bound proton pump : Studies of charge transfer reactions in cytochrome c oxidase
Abstract : In cellular respiration, electron transfer from the breakdown of foodstuff is coupled to the formation of an electrochemical proton gradient. This is accomplished through proton translocation by respiratory complexes, and the proton gradient is subsequently used e.g. to drive ATP production. READ MORE
