Abstract

We report stable and reproducible switching and memory effects in Self-Assembled Monolayers (SAMs). We demonstrate realization of negative differential resistance (NDR) and charge storage in electronic devices that utilize single redox-center-contained SAM as the active component; and compare the effects of various redox centers to switching and storage behavior. The devices exhibit electronically programmable and erasable memory bits with bit retention times greater than 15 min at room temperature.

    Self-assembly has been proven to be an effective way to produce porous materials, which, when used as catalysts or supports, pave new roads for designing heterogeneous catalysts at the levels of both surface structure and porosity (Gorzny, Walton, & Evans, 2010; Lim et al., 2010; Long et al., 2010). The growing interest which self assembly has attracted during the last decades is provoked by the diverse applications that have been found as model systems in physics, chemistry and biology and also tested as building blocks in fabrication of biochips (Nelson et al., 2001), optoelectronic devices (Chen, Su, Wang, & Reed, 2003) and sensors (Alvarez et al., 2003; Schreiber, 2000; Ulman, 1996; Watanabe & Kajikawa, 2003). Alkanethiols and disulfides are well known to self-assemble and form ordered monomolecular films on noble metal surfaces (Poirier & Pylant, 1996; Poirier, 1997).

    Moreover, if compared with similar volatile organic memories, this device does not show a good retention time because was performed by organic self-assembled monolayers fabricated with donor and acceptor electrons molecular groups. Despite that, the peak current for this devices is less than 2.5 nA, very small compared with our memory device [22]. In conclusion, we have investigated and manufactured electrical switching semiconductor device based on acid MR thin film.
