초록

We enhanced the conductivity of PEDOT-PSS by mixing with glycerol and fabricated the low contact resistance of source and drain[S/D] electrodes of OTFT with PEDOT-PSS by ink-jetting printing. The contact resistance was much smaller by seven times than Au with $200k{\Omega}$ at $V_G=-5V$. For the bottom contacted OTFTs, the performance was comparable to OTFTs with Au electrodes with the field effect mobility of $0.2\;cm^2/V s$.
