16.The proposal leakage mechanisms in BST thin films include Schottky emission, Fowler–Nordheim tunneling, Poole-Frenkel emission, and SCLC. In order to confirm that leakage current in the high electric field regions shows SCLC behavior, we used the other three mechanisms to fit our data. The results showed that our data were not in agreement with the other three mechanisms.

20.From the vs and vs plots, we can get the temperature range from 150 to where the leakage current still shows SCLC behavior in the high electric field regions.
21.The used here is measured in the case of a negatively biased electrode with an electric field of . The used here is also measured at .
22.Further evidence is that from 150 to , the and the increase with increasing temperature, results in disappearance of the PTCR effect.
