Testing method for carrier mobility of insulating polymers

A testing method for carrier mobility of insulating polymers, wherein the testing method for carrier mobility of insulating polymers is based on a testing device for carrier mobility of insulating polymers, and the testing device for carrier mobility of insulating polymers comprises:

• a first box;
• a second box, disposed inside the first box, wherein a partition plate is disposed in the second box, and the second box defines a first space and a second space through the partition plate;
• a sample frame, configured to fix a sample, wherein the sample frame is disposed in the first space;
• an X-ray source, disposed in the second space, and configured to generate and emit X-rays to irradiate the sample, to thereby excite generation of carriers in the sample;
• a voltage generation component, in line connection with the sample, to apply a triangular wave voltage to two ends of the sample, to thereby make the carriers generated in the sample move;
• and
• a current detection component, connected to the sample, to thereby collect current signals of the sample generated by movement of the carriers;
• and
• wherein the testing method comprises:
• irradiating the sample by using the X-rays generated through the X-ray source, to generate the carriers in the sample, exciting the carriers to move by using the X-rays, applying the triangular wave voltage on the sample, and measuring a carrier mobility of the sample by measuring induced current.
