  2. 1. Gas sensitivity of modified metal-oxide-semiconductor devices

    Author : Eva Hedborg Karlsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : 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. READ MORE

  4. 2. Surface and Interface Phenomena Studied with Pd Metal-Oxide-semiconductor Structures : Adsorption, catalytic reactions, hydrogen sensing and Pd restructuring

    Author : Mats Eriksson; Wolfgang Göpel; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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. READ MORE

    Abstract : 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. READ MORE
