Zinc-stimulated outdiffusion of iron in InP

Abstract
High-resistivity InP (108 Ω cm) can be grown by means of metal organic vapor phase epitaxy using ferrocene as a dopant source. Adjacent zinc-doped layers of InP annihilate the resistivity of the (intentionally) iron-doped InP. The presence of Zn dramatically enhances outdiffusion of iron out off intentionally iron-doped layers of InP into the Zn-doped InP. Diffusion of Zn into the iron-doped InP is also observed.
