  2. 1. Radiation Hardness of 4H-SiC Devices and Circuits

    Author : Sethu Saveda Suvanam; Anders Hallén; Carl-Mikael Zetterling; Ulrike Grossner; KTH; []
    Keywords : Silicon carbide; radiation hardness; protons; gamma radiation; bipolar junction transistors; aluminium oxide; surface recombination.; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Advances in space and nuclear technologies are limited by the capabilities of the conventional silicon (Si) electronics. Hence, there is a need to explore materials beyond Si with enhanced properties to operate in extreme environments. In this regards, silicon carbide (4H-SiC), a wide bandgap semiconductor, provides suitable solutions. READ MORE

  4. 2. Impact of Ionizing Radiation on 4H-SiC Devices

    Author : Muhammad Usman; Anders Hallén; Einar Örn Sveinbjörnsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon carbide; ionizing radiation; bipolar junction transistors; reliability; surface passivation; high-k dielectrics; MIS; radiation hardness;

    Abstract : Electronic components, based on current semiconductor technologies and operating in radiation rich environments, suffer degradation of their performance as a result of radiation exposure. Silicon carbide (SiC) provides an alternate solution as a radiation hard material, because of its wide bandgap and higher atomic displacement energies, for devices intended for radiation environment applications.
