Sažetak

The conductivity and the Hall coefficient have been measured on several high resistivity p-type and n-type germanium samples at reduced temperatures as function of the charge induced by the field effect. The results are compared with the three carrier theoretical expressions of Petritz, using surface mobilities based on the theory of diffuse surface scattering. Comparison is also made with theoretical expressions when surface mobilities are taken equal to bulk mobilities of corresponding carriers. Calculations based on diffuse surface scattering agree fairly well with the experimental data for majority carriers ,in accumulation and depletion layers. For minority carriers in the inversion layers experimental and theoretical data disagree for both specular and diffuse surface scattering models.
