  1. 1. Methods for Characterization and Optimization of AlGaN/GaN HEMT Surface Passivation

    Författare :Martin Fagerlind; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; surface states; surface passivation; annealing; processing; AlGaN GaN HEMT; MIS-capacitor;

    Sammanfattning : The Gallium Nitride based high electron mobility transistor is rapidly improving and is emerging as a viable alternative for use in high power applications operating in the microwave frequency domain. The suitability of the AlGaN/GaN material system is due to the possibility to grow epitaxial heterostructures that provide; high electron mobility, high electron saturation velocity, high carrier density and a high dielectric breakdown field.

  3. 2. Silicon carbide field-effect devices studied as gas sensors for exhaust gas monitoring

    Författare :Peter Tobias; Ignaz Eisele; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon carbide; high temperature; gas sensors; field effect devices; MISdevices; Schottky diodes; experimental design; reaction kinetics; mass transport; car exhaust; multipoint injection; response times; cylinder specific; on-board diagnosis;

    Sammanfattning : Metal-insulator-silicon carbide (MIS) structures have been studied as gas sensors. We have investigated how the sensors detect gases, how fast they do that, and how they could be used for exhaust gas monitoring.We have prepared simple field-effect devices, MIS-capacitors and Schottky diodes, on silicon carbide with platinum gates.
