Book excerpt: The Hall coefficient and specific conductivity were determined on single n-type tellurium-doped gallium phosphide crystals in the 77 - 600K temperature range to establish the temperature-dependence of these values and to gain further insight into the mechanism of carrier scattering. The temperature-dependence of the electrical conductivity and of the Hall coefficients in typical crystals are shown. On the basis of the experimental data, the relation between electron mobility and temperature was determined. Typical results are presented. The main determining factor in the scattering mechanism is scattering on optical photons (polar scattering); however, in the low end of the temperature range investigated and in instances where the crystal is grossly contaminated, other factors, such as space charge, also become significant. The temperature-dependence of the Hall effect suggests a donor level with an ionization energy of approximately 0.11 electron-Volt.
