ABSTRACT:
Process for the production of semiconductor crystals with high resistivity of the CdXTe type, wherein X=Zn, Se, ZnSe or 0, characterized in that it consists in carrying out a multiple doping with iron and with at least one second doping element selected from the group formed by the elements of group III of the periodic chart of the elements.
