| Abstract: | The principle and features of the spreading resistance method are described. This method has been successfully applied to the measurement of the microregion conductivity for the first time. An identification system for microregion location has been designed. The relationships between the microregion resistance and the constitution of semiconducting ceramics, including Ba(Sn1-xSbx)O3, ZnO and BaTiO3 have been investigated and meaningful results have been obtained. From the relations between microregion Ba/(Sn + Sb) and P, in the Ba (Sn1-xSbx)O3 system, it can be seen that SnO3 and BaSnO3 are of low-resistance phase while Ba3Sn2O3 is of high-resistance phase. |
