Abstract
A detection method and device for low carrier mobility of an insulating material, relating to a technical field of electrical property testing of insulating polymer materials, includes following steps: fixing a sample; applying a triangular wave voltage to both ends of the sample; irradiating the sample by an X-ray to generate carriers inside the sample, in which, the carriers is driven to move under an action of the triangular wave voltage, and an irradiation process of the X-ray coincides with a rising phase of the triangular wave voltage; acquiring a current signal of the sample under the action of the triangular wave voltage; and calculating a carrier mobility based on the current signal. The detection method and device for low carrier mobility of the insulating material achieves accurate detection of behaviors of the carriers inside the insulating material by combining X-ray excitation with voltage signal analysis.
