Abstract
Recombination at dislocations located in the space charge region (SCR) of a Schottky diode has been previously evidenced by EBIC contrats experiments [1] in the case of non intentionally n type CdTe. A depth-dependent recombination probability was, then, phenomenologically ascribed to the dislocation, in order to fit theoretical EBIC curves as a function of the beam accelerating voltage Eo obtained for dislocations perpendicular to the surface, with experimental ones. A variable radius ε(z) was assigned to the recombination cylinder which described the dislocation and within which the recombination efficiency was taken equal to 100% [2] .
