| Abstract(in English) | Gold is generally used for the source and drain electrodes of organic thin-film transistors (OTFTs). However, the cost of gold is expensive when considering the practical applications such as flexible displays. Here, we applied copper instead of gold for the bottom-contact (BC) of OTFTs for lowering the fabrication costs. The reduction of contact resistance between source-drain electrodes and a organic semiconductor is crucial to achieve the high performance for the BC-OTFT. The mobility of the saturation region using polymer semiconductor Poly (2,5-bis(3-hexadecyl thiophene-2-yl) thieno [3,2-b] thiophene (PB16TTT) is estimated to 0.12 cm2Ns. Fabricated TFTs with PB16TTT as semiconductor layer have no hysteresis in transfer curves, low subthreshold swing compared to those with Pentacene as semiconductors. |
