Structural and electrical characterization of a block copolymer-based unipolar nonvolatile memory device

Abstract

Electronic devices based on a series of synthesized block copolymers are demonstrated. In particular, a block copolymer system with a lamellar structure exhibits unipolar switching behavior. This study provides a simple strategy based on the adjustment of the block ratio in block copolymers to control the polymer morphology and thus the electrical and switching properties of polymer-based memory devices.

Keywords: anionic polymerization; block copolymers; non-volatile memory; unipolar switching.
