| Uses and Features | Thin-film electrical conductivity measurements are widely used in both research and industrial production. By characterizing thin-film conductivity, researchers can gain deep insights into a material’s physical properties and fabrication processes, thereby providing crucial support for advances in materials science and engineering technology. This apparatus employs the four-electrode (or two-electrode) method to measure the surface conductivity of thin films. The method offers advantages such as simple operation and high accuracy, making it suitable for a wide range of thin-film materials. Four-electrode configuration: In the setup, the four electrodes are connected to the counter electrode, reference electrode, sensing electrode, and working electrode of the electrochemical workstation, respectively, ensuring good contact between the thin film and all four electrodes. Two-electrode connection method: In the setup, the two middle electrodes are connected to the counter electrode and the reference electrode of the electrochemical workstation, while the sensing electrode and the working electrode are also connected. The thin film is in good contact with the two middle electrodes. The membrane dimensions are 32 × (40–50) mm. Selected articles published using this device: 1. Ning, Tianshu, et al.
