Thermally-stable resistive switching with a large ON/OFF ratio achieved in poly(triphenylamine)

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 × 10(8), a long retention time exceeding 8 × 10(3) s and a wide working temperature range of 30-390 K.
