Abstract
Hall effect and conductivity measurements are performed, in the case of tellurium, on samples containing a high density of a screw dislocations and on reference samples. Comparison of these measurements shows that a screw dislocations are responsible for a strong free carrier mobility decrease. A discussion of the results, based on theoretical calculations of the free carrier mobility permits to conclude to a piezoelectric scattering mechanism.Keywords
