摘要
For an analysis of the mechanism of carrier injection in the structure of bottom contact organic thin-film transistor (OTFT), Al blocking layer was applied to the source/drain electrode in variety of ways in the fabrication of bottom contact OTFT. From the comparison of the transfer characteristics of the OTFTs with different electrodes, it is obvious that the main direction of carrier injection is mainly dependent on the thickness of electrode. When the electrodes become thicker and thicker, the main carrier injection path is expected to be located at the side of the electrodes as well as the top of the electrodes.
