抄録: | We report for the first time organic n-type nonvolatile memory transistors based on a fullerene (C_<60>) semiconductor and an electron-trapping polymer, poly(perfluoroalkenyl vinyl ether) (CYTOP). The transistors with a Si++/SiO_2/CYTOP/C_<60>/Al structure show good n-type transistor performance with a threshold voltage (V_<th>) of 2.8 V and an electron mobility of 0.4 cm^2 V^<−1> s^<−1>. Applying gate voltages of 50 or −45 V for about 0.1 s to the devices induces the reversible shifts in their transfer characteristics, which results in a large memory window (ΔV_<th>) of 10 V. A memory on/off ratio of 10^5 at a small reading voltage below 5 V and a retention time greater than 10^5 s are achieved. The memory effect in the transistor is ascribed to electrons trapped at the CYTOP/SiO_2 interface. Because of the use of high-electron-mobility C_<60>, the switching voltages of our memory transistors become significantly lower than those of conventional memory transistors based on pentacene. |
