Abstract

Thermally stable poly(triphenylamine) (PTPA) synthesized by an oxidative coupling reaction is used as the functional layer in memory devices, which exhibit non-volatile bistable resistive switching behavior with a large ON/OFF ratio over 5 × 10⁸, a long retention time exceeding 8 × 10³ s and a wide working temperature range of 30–390 K.
