Organic field-effect transistors (OFETs) have excellent characteristics such as solution processability, high flexibility, and good ductility, and are key building blocks for future large-area flexible electronic devices. In recent years, OFET devices have received much attention due to their important role in evaluating device performance and meeting practical requirements. According to Shockley's hypothetical model, the ideal organic field effect would exhibit a linear transfer curve characteristic with mobility independent of gate pressure (as shown in Figure 1). However, in practical applications, devices often exhibit non-ideal behaviors such as "dual slope", "exponential", and "super-linear", resulting in a direct correlation between mobility and applied gate voltage (as shown in Figure 1b-d). These non-ideal operating characteristics seriously affect the reliability of the obtained device performance parameters such as mobility and threshold voltage, and hinder the correct understanding of the device operating mechanism.
