✦ Synopsis
Photoelectrochemistry of Highly Zn-Doped Pyrite as Compared with Isostructural FeS 2 .
-Incorporation of small quantities of Zn (¡5•10 20 cm -3 ) into FeS 2 leads to a significant change of relevant photoelectrochemical properties: the width of the forbidden energy gap, the quantum efficiency for the generation of photocurrents, and the photocurrent spectrum. Zn atoms on iron lattice sites appear to be responsible for both the changes in the electronic structure and the restructuring of interfacial pathways for electron transfer. -
