The critical volume fraction for conductivity percolation in the di-phasic system (CdTe) 1-x Te x has been determined using atomic force microscopy. The onset for rapid increase in the electrical conductivity is found at a volume fraction of Te of about 0.4. According to previous theoretical calculations this value is characteristic of a system with two-dimensional symmetry. It is also found that the Te phase grows in the form of columns, which explains the observed critical volume fraction value for percolation in the conductivity measurements. © 1994 American Institute of Physics.
