Italian technological district for the engineering of polymeric and composite materials and structures
As part of the Po.Di.Me. project, several functional polymer systems have been identified that can be used to create non-volatile memories with bistable behavior. The main characteristic of these materials is that, when subjected to an electric field, they exhibit hysterical behavior that does not vary over time, even when subjected to a high number of read and write cycles. Particular emphasis has been placed on optimizing deposition techniques and process methodologies to obtain low-cost devices that are easy to industrialize.
The research led to the creation of prototype two-electrode devices with crossbar architecture and memory devices with an architecture similar to field-effect transients (FETs) to test the feasibility of electronic applications based on organic semiconductors.
Numerous technologies for the deposition and structuring of organic materials were identified, and their potential industrial applications were considered, while simultaneously evaluating their technological limitations and dimensional resolution as a function of the materials used.
Furthermore, the project developed molecular modeling of the systems of interest using numerical methodologies suitable for simulating macromolecular systems.
Thanks to the feasibility studies conducted, the fabrication process for fully organic memories was developed using organic conductor deposition techniques as a possible alternative to metal electrode deposition.
