| Abstract: | The optical cross-section σn0(hv) and σp0(hv) associated with the (Fe3+ ? Fe2+) deep level have been measured by Deep Level Optical Spectroscopy in n-type Fe doped samples of InP. Optical transitions are interpreted as transitions from the Fe2+ ground state to the Γ and L point minima of the conduction band for σn0(hv) and from the valence band to the ground and excited state for Fe2+ for σp(hv). A theoretical model which accounts for the main features of the experimental data is proposed. |
