文摘

Organic non-volatile memory devices with significantly enhanced retention are explored with C₆₀ thin-film transistors containing silver nanoparticles (Ag-NPs) within gate dielectrics as charge storage nodes. Dipolar self-assembled monolayers covering Ag-NPs effectively prevent stored charges from being lost by providing an additional energy threshold for back-tunneling process. This enables long retention even with ultrathin tunneling dielectric layers, providing a simple means to realize long retention without causing an excessive increase in operation voltage.
