Abstract
In contrast with the other interfaces involving deposition of 3d transition metals on III-V semiconductors (mostly GaAs), the Fe/InAs(1 0 0) interface exhibits magnetic properties even at the lowest coverage (1 monolayer, ML) investigated. The reactivity of the interface is also lower compared with Fe/GaAs. It involves formation of an interface compound of approximate stoi chiometry of FeAs mixed with metallic In islands for Fe coverages lower tha n 3 ML, followed by the growth of relaxed bulk alpha -Fe in a Vollmer-Weber mode.
