1. Physics of palladium metal-oxide-semiconductor devices
Abstract : This thesis Palladium gate metal-oxide-semiconductor (PdMOS) devices are used as hydrogen sensors. It is shown that the sensitivity is only partly due to the change of the effective work function of the Pd gate on hydrogen adsorption. Sodium ion drift experiments have shown that hydrogen-sodium interactions occur in PdMOS devices. READ MORE

4. Electrical Characterization of Metal-Oxide-Silicon Structures with Ultra Thin Oxide Layers
Abstract : Metal-oxide-semiconductor (MOS) structures with very thin (2 - 4 nm) oxide layers thermally grown on silicon have been electrically characterized regarding oxide and interface defects and concerning the direct tunnel current through the oxide. This thesis comprises eight papers which deal with the appearance of oxide charge during electrical stress (papers A, D, E), the beneficial effect on the defect density of low-temperature (up to 350 °C) post-metallization annealing (PMA) (paper A, B, C, G), and the effect of temperature and choice of metal for the tunnel current (paper F, H).

5. Silicon nanowire based devices for More than Moore Applications
Abstract : Silicon nanowires (SiNW) are in the spotlight for a few years in the research community as a good candidate for biosensing applications. This is attributed to their small dimensions in nanometer scale that offers high sensitivity, label-free detection and at the same time utilizing small amount of sample. READ MORE
