The chosen geometry of antimony probes in contact with the Te-samples were triangles, rectangles, semicircles and segments of circles whose each pair was of 2 types of probe extension. The first was the uniform electrode width configuration in which the metal (Sb) electrode width was continuous at the edge of the Te-sample while the second was the differential electrode configuration is which the metal electrode width was discontinuous as the edge of the Te-sample region. The results showed that the surface density-voltage characteristics were linear in every case. The rectangular electrode pair gave the least values, followed by the semi-circular pair and finally the triangular pair. In the latter 2 cases, the results for both uniform and differential electrode width configuration were practically the same. ER -
