Non-volatile organic memory applications enabled by in situ synthesis of gold nanoparticles in a self-assembled block copolymer

A block copolymer with Au nanoparticles is shown to exhibit a memory effect, with the An nanoparticles acting as floating charge storage components for the holes from pentacene in a metal-pentacene insulator-silicon (MPIS) structure (see figure). This novel structure displays a large memory window of 2.1 V after programming and erasing modes, and excellent retention ability.
