Test methods for measuring resistivity of electrically conductive ceramic thin films with Van der Pauw method

This technical specification outlines a standardized procedure for determining the electrical resistivity of conductive ceramic thin films utilizing the van der Pauw method. The approach provides a systematic framework for preparing test specimens and measuring their four-terminal resistance values, which are essential for calculating intrinsic resistivity independent of sample geometry. The methodology addresses key aspects such as contact placement, measurement conditions, and data interpretation to ensure repeatability and accuracy across different laboratories. It specifies requirements for the equipment used and details the mathematical relationships derived from the Hall effect principles that govern the measurement process. By adhering to these defined steps, manufacturers and researchers can reliably characterize the electrical properties of ceramic materials used in various electronic components and sensors. The protocol serves as a reference for quality control and material development, facilitating consistent evaluation of thin film performance in industrial applications and scientific research without prescribing specific material compositions or device designs.
