| Abstract;Molecular electronic devices were fabricated with thiol derivatives as redox-active component. This molecules have a thiol radical to allow monolayer formation by the self assembly method, and then this self assembled monolayer (SAM) were inserted between patterned Pt bottom electrode (30 nm) and Ti (5 nm)/Al (30 nm) top electrodes in crossbar array architectures. Before self assembly process, the substrate was treated by a piranha solution or a UV-ozone treatment. From contact angle measurements, before forming SAM, both the substrates treated by the piranha solution and the UV-ozone were hydrophilic condition. After forming SAM, the substrates were maintained with hydrophobic condition in case of the octadecanethiol (C18SH) and hydrophilic condition in case of the 11-mercapto-1-undecanol (HSC11OH). Such results were shown that the SAM was well packed. Also, the current-voltage (I-V) characteristics of the SAM devices along the direction vertical to substrate were measured. (author abst.) |
