Abstract: Photocapacitance, DLTS, optical absorption and photoluminescence data are presented for iron- and iron-germanium-doped Czochralski single-crystal InP. The results demonstrate that the Fe 2+ to Fe + transition is not present within the InP band gap. A feature observed in photocapacitance and optical DLTS is attributed to the presence of the Fe 4+ charge state, and features associated with the well known Fe 3+ and Fe 2+ states also occur. Photoluminescence measurements show an iron-related band near 0.5 eV, not previously reported in the literature.
