AbstractCuTCNQ (TCNQ=7,7,8,8-tetracyanoquinodimethane) is a resistive switching charge-transfer complex which can be used for organic nonvolatile memories. In this contribution we report on a thorough investigation of the electrical switching of CuTCNQ memories. Our memories currently achieve an endurance of up to 10000 write/erase cycles with a clear distinction between ON and OFF reading currents. ON and OFF threshold voltages follow a Gaussian distribution. Temperature dependent measurements of CuTCNQ based organic memories show a semiconductor like behavior for the ON state. The retention time of the ON state exceeded 60 hours at room temperature. Electrical switching of CuTCNQ memories in air was virtually not affected by temperatures up to 80°C, but becomes erratic at 120°C. The CuTCNQ material itself already starts to decompose around 200°C in presence of oxygen as shown by thermogravimetric analysis.

ABSTRACTThe doping effects on optical and electrical properties of polysilanes have been investigated by in-situ Measurement. An optical absorption associated with σ–σ* transition was observed near 330 nm for polymethylphenylsilane. By iodine doping, a new absorption was observed at the longer wavelength around 420 nm, which should originate from the charge transfer between dopant and Σ-conjugated system. Similar spectral changes have also been observed for most of investigated linear polysilanes.Furthermore, we have found drastic spectral change upon iodine doping into polysilane with p-N,N-dimethyIaminophenyI substituent. It has very strong absorption up to 700 nm. It Might originate from a strong interaction between the substituent and iodine. At the same time, Σ-conjugation Might also play a significant role on doping into this system.
