Analysis of the current transport mechanism of copper phthalocyanine Organic Static Induction Transistor

According to the test results of current-voltage characteristics, the current transport mechanism of Organic Static Induction Transistor (OSIT) using copper phthalocyanine (CuPc) as active layer is investigated. The transport mechanism of small current region and especially medium-large current region are all analyzed. Depending on in-depth theory analysis of experiment data about current-voltage characteristics, the current-voltage characteristic of OSIT exhibits exponential relationship in small current region. However, the current-voltage characteristic in medium-large current region is governed by with exponential trap distribution.
