5. 발표 내용

The current record for high-speed organic transistors is held by the vertical organic thin film transistor (VOTFT) due to 

very short vertical carrier paths and simple device structures for diverse applications. Electrochemically anodized aluminum oxide

is used in vertical organic permeable base transistor (vertical OPBT) and vertical organic field-effect transistor (VOFET) for 

excellent dielectric structures and interface modifications. For the first time we show the successful enhancement of vertical OPBT 

with the electrochemically-oxidized base electrode by anodization. Leakage currents and parasitic capacitances are significantly 

reduced, paving the way to even the highest transit frequencies amongst the reported organic transistors. For the VOFET, 

we use electrochemically-oxidized insulating layer to form the charge blocking layer at the vertically-stacked source-drain interface. 

Therefore VOTFTs with low leakage current, high on/off current ratio, high-speed, and low operating voltage are demonstrated with 

the electrochemically anodized electrodes.
