Abstract

A photoconductivity peak at 0.44 eV is observed in Fe-doped InP. This peak is attributed to electrons which are optically excited from the Fe²⁺⁵E ground state to vibronic levels of the ⁵T₂ excited state, and thermally excited from there to the conduction band. The lineshape is nearly Gaussian and is well fitted by assuming a vibronic coupling energy of about 0.06 eV in the ⁵T₂ state. In analogy with results in the II–VI compounds this coupling may be dominated by interaction with non-symmetric lattice modes which produce a dynamic Jahn-Teller effect.
