Abstract: | The Hall mobilities (conductivity type) measured on many Fe-doped InP wafers have been used as a parameter for material assessment.
The samples can essentially be assigned to three groups. Interpretation of the experimental data is given for each group of
samples. Furthermore, we report the results of electrical measurements on annealed InP and show the kind of correlation existing
between the electrical characteristics of as-grown and annealed InP. Finally, we report a study on the homogeneity of Fe-doped
InP on a macroscale. It is seen that the experimental resistivity profiles along the wafer diameters are a function both of
the Fe and shallow inpurities profiles. |
