Nickel ohmic contacts to p- and n-type 4H-SiC

The first demonstration of Ni ohmic contacts to both p^sup +^ and n^sup +^ 4H-SiC formed by ion implantation is reported. Sample preparation conditions are described and experimental results presented. Specific contact resistances in the range of 10^sup -4^ Ωcm^sup 2^ and 10^sup -6^ Ωcm^sup 2^ for p...

Zusammenfassung:The first demonstration of Ni ohmic contacts to both p^sup +^ and n^sup +^ 4H-SiC formed by ion implantation is reported. Sample preparation conditions are described and experimental results presented. Specific contact resistances in the range of 10^sup -4^ Ωcm^sup 2^ and 10^sup -6^ Ωcm^sup 2^ for p^sup +^ and n^sup +^ 4H-SiC, respectively, have been determined by the transfer length method.
