Carbon nanostructures in organic WORM memory devices

Author affiliations

Abstract

We briefly review recent developments concerning the use of carbon nanostructures in polymer composite thin films for write-once-read-many-times memory devices. We also show that carbon sphere/poly(vinylphenol) composites prepared with the addition of hexadecyltrimethylammonium bromide as a surfactant show better carbon sphere dispersion, allowing in principle a memory device size reduction. Devices constructed with surfactant added carbon-sphere/poly(vinylphenol) composites allow writing the ON state in ∼200 ns and the write operation consumes 5 × 10−5 J cm−2 when a pulse with an amplitude of 5 V and a length of 1 μs is used.
