Abstract Scope |
Nanoparticles of BaTiO3 were modified with yttrium salt, in order to enhance its electronic properties. Graph theory was applied for calculation of capacitance change at the interface between grains under the influence of the applied voltage and electroconductivity at nanocrystal diamonds. Measurements were performed on bulk samples, showing that modified nano- BaTiO3 can retain stability up to 100V. Grains were presented as edges in graph between vertices and capacitance change was successfully calculated on grain boundaries, based on different number of neighboring grain and applied DC bias. Calculations presented as 1D, 2D and 3D cases were performed, proving that graph theory could be applied to characterize intergranular relations based on bulk measurements. Based on our findings, it is obvious that this approach could solve measurement problems, which cannot be performed on nano level, opening new perspective in miniaturization of electronic materials. |
