However, there is still challenging issue for the realization of logic circuits with nano-scaled array devices in which organic molecules can be used to transfer and process an electronic signals. In order to design and realize such nano-scaled molecular array devices, several requirements should be satisfied such as rectifying molecules, device fabrication, immobilization of organic molecules, and implementation of logic device.
Here, we report the simple fabrication process for making a 3x3 molecular rectifying array device containing 9 nano via holes and I-V characterization of the rectifying molecule at room temperature.
Also, we demonstrate that this 3x3 array device containing newly synthesized electron Donor-sigma-Acceptor-thiolate molecule can be used as electronically configurable OR/AND logic gate.
In addition, we like to briefly introduce a development of molecular memory device such as designing organic memory materials and soft lithography for a device fabrication in ETRI.
