Previous results on dislocations in piezoelectric insulating crystals are extended and the possibility of trapping charges at the core of a given dislocation is discussed. The electrical potential associated with a dislocation is explicitly calculated for Te crystals. The case of screening by free carriers in a semiconductor is then treated and a general solution for the potential is given. Physical consequences are described.
