  7. 10. Ohmic Contacts for High Temperature Integrated Circuits in Silicon Carbide

    Författare :Katarina Smedfors; Carl-Mikael Zetterling; Niklas Rorsman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : In electrical devices and integrated circuits, ohmic contacts are necessary and a prerequisite for the current transport over the metal-semiconductor junctions. At the same time, a desired property of the ohmic contacts is to not add resistance or in other way disturb the performance. LÄS MER
