Volatile static random access memory behavior of an aromatic polyimide bearing carbazole-tethered triphenylamine moieties

Volatile static random access memory behavior is observed on a functional polyimide bearing hexafluoroisopropylidene-diphthalimide parts as the electron acceptor and carbazole-tethered triphenylamine moieties as the electron donor with an ON/OFF current ratio of 105 and a switching time less than 20 ns. Molecular simulation is conducted to clarify the carrier transport process and memory mechanisms in this electroactive polyimide.252
