Figure 4From: Metal work-function-dependent barrier height of Ni contacts with metal-embedded nanoparticles to 4H-SiC1/ C2 versus reverse voltage characteristics. 1/C2 versus reverse voltage for n-type of Ni film without NPs (Ref), Ni film with embedded Au-NPs (NP-1), and Ni film with embedded Ag-NPs (NP-2) to 4H-SiC at a frequency of 1 MHz at 300 K. The contact area is 3.14 × 10-2 cm-2.Back to article page
