Nanoscale Study of Perovskite Solar Cells for Efficient Charge Transport
… effect of temperature, humidity and water on the grain boundary potential and charge transport within the grains of pervoskite films prepared by sequential deposition technique. Grain boundary potential of perovskite films exhibited variation in electrical properties with humidity level, …

Domain and Grain Boundary Structural Effects on the Resistivity Behavior in Donor Doped, PTCR Barium Titanate
… c}$). This is accomplished by development of a grain boundary potential barrier, the height of which is low at temperatures below T$\sb{\rm c}$ and high at temperatures above. The properties of the grain boundary region, its structure, chemical composition and related defect structure are not …

Degradation mechanisms of barium titanate based thick film capacitors
… either on simple vacancy movement or a reduced grain boundary potential barrier height are suggested. It has been found that an electronic conduction model based on reduced grain boundary barrier height is more reasonable than that of simple vacancy induced current model.

Impedance characteristics and grain boundary effects in titanate-based multilayer ceramic capacitors
… gain a better understanding of the effects that grain boundaries have on conduction in multilayer ceramic (MLC) capacitors. Electrical measurements were made so that current-voltage curves and impedance plots could be constructed. It was found that the current-voltage curves of new COG and X7R …
