Heterojunctions between Silicon and the Semiconducting Metal Silicides β-FeSi2 and MgSi2

Abstract

The current-voltage dependences of heterojunctions between the silicon and the semiconducting metal silicides β-FeSi2 and MgSi2, prepared by ion-beam synthesis, followed by rapid thermal annealing, are reported. It was found that the anisotype junctions showed a rectifying behavior, reflecting the heterojunctions energy band diagrams, constructed on the base of the previous optical and structural investigations.
