摘要：

We have fabricated a field effect transistor structure using the charge-ordered (CO) organic material alpha-(BEDT-TTF)(2)I-3 to investigate the effects of electrostatic carrier injection. We have observed both n-type and bipolar behaviors in the CO state, whereas, previously, only n-type characteristics were reported. The present results indicate that the transfer characteristics for a negative gate voltage, i.e., hole transport characteristics, are highly dependent on the interface conditions between alpha-(BEDT-TTF)(2)I-3 and the electrodes and/or gate insulator. In addition, the activation energy of the CO state is essentially independent of V-SG. This result suggests the robustness of the CO state to electrostatic charge carrier injection.
