It has recently been reported that high-resistivity Fe-doped InP wafers can present very different compensation conditions. This gives rise to different mobility and conductivity characteristics. The high-resistivity InP samples can basically be assigned to three categories: (A) samples with high mobilities and thermal activation energies ≈ 0.60 eV; (B) samples with intermediate mobilities and activation energies below 0.60 eV; (C) samples with low mobilities and activation energies around 0.40 eV. Some reasons at the basis of the different physical properties exhibited by Fe-doped InP have already been discussed. In this work, new characterization techniques were applied in order to investigate other deep levels beside the main deep level due to iron.

Abstract
It has recently been reported that high-resistivity Fe-doped InP wafers can present very different compensation conditions. This gives rise to different mobility and conductivity characteristics. The high-resistivity InP samples can basically be assigned to three categories: (A) samples with high mobilities and thermal activation energies ≈ 0.60 eV; (B) samples with intermediate mobilities and activation energies below 0.60 eV; (C) samples with low mobilities and activation energies around 0.40 eV. Some reasons at the basis of the different physical properties exhibited by Fe-doped InP have already been discussed. In this work, new characterization techniques were applied in order to investigate other deep levels beside the main deep level due to iron.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
