The distributions of polar dislocations appearing in surface and volume deformation zones of indentations on {111}Cd, {-1-1-1}Te and {110} surfaces of CdTe bulk crystals are studied. Distinct CL contrast properties proved in CdTe for A(g)- and B(g)-type dislocations are utilised to recognise Cd(g) and Te(g) dislocation segments in the deformation-induced defect configurations. The microscopic spatial glide geometries as caused by indenting the low-indexed surfaces are theoretically developed within the framework of an advanced <110> glide prism model. Comprehensive results gained by means of depth-resolved CL microscopy fully confirm the concept of 3D glide prism formation. The experimental findings give evidence for a coexistence of Cd(g) and Te(g) dislocations in tangential as well as tetrahedral deformation zones. From that, correlated propagation of polar dislocation segments during plastic flow has to be concluded.
