1. Physics of palladium metal-oxide-semiconductor devices
Sammanfattning : 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. LÄS MER
2. Gas sensitivity of modified metal-oxide-semiconductor devices
Sammanfattning : Gas sensitive thin metal-oxide-semiconductor (MOS) structures have been used to study the effect of different modifications of the gate metal. In order to increase the selectivity of the gas sensor photoresist was used as a gas permeable membrane. LÄS MER
3. Surface and Interface Phenomena Studied with Pd Metal-Oxide-semiconductor Structures : Adsorption, catalytic reactions, hydrogen sensing and Pd restructuring
Sammanfattning : The electronic properties of palladium metal-oxide-semiconductor (Pd-MOS) structures are highly sensitive to hydrogen over a large pressure range. Such devices have been found useful in several applications, e.g. as a chemical sensing element in the so called electronic nose. LÄS MER
4. Detection and removal of traps at the SiO2/SiC interface
Sammanfattning : The interface between silicon dioxide (SiO2) and silicon carbide (SiC) is at the heart of the SiC metal-oxide-semiconductor field-effect (MOSFET) transistor. The technology to produce a high quality SiO2/SiC interface does not exist today, hampering further development of the SiC MOSFET. LÄS MER
