Abstract

A tunable Fabry–Pérot resonator is realized using metal–insulator–metal structure, in which the insulator is chitosan hydrogel. The chitosan swells in response to changes in relative humidity; this change affects transmissive structural color of the multilayer structure. This tunable resonator is utilized for a humidity sensor combined with a photovoltaic cell. The change in current through the photovoltaic cell provides rapid precise measurement of relative humidity, and the change in color of the multilayer provides an approximate, remotely‐readable estimate. The response requires no power, so the device has numerous sensing applications. [ABSTRACT FROM AUTHOR]

21. Resistive Switching Memory Based on Bioinspired Natural Solid Polymer Electrolytes

Author

Raeis Hosseini, Niloufar and Lee, Jang-Sik

Abstract

A solution-processed, chitosan-based resistive-switching memory device is demonstrated with Pt/Ag-doped chitosan/Ag structure. The memory device shows reproducible and reliable bipolar resistive switching characteristics. A memory device based on natural organic material is a promising device toward the next generation of nonvolatile nanoelectronics. The memory device based on chitosan as a natural solid polymer electrolyte can be switched reproducibly between high and low resistance states. In addition, the data retention measurement confirmed the reliability of the chitosan-based nonvolatile memory device. The transparent Ag-embedded chitosan film showed an acceptable and comparable resistive switching behavior on the flexible plastic substrate as well. A cost-effective, environmentally benign memory device using chitosan satisfies the functional requirements of nonvolatile memory operations.

Abstract

A phase change material (PCM) is implemented in a memristive device as an emerging technology for the next generation of nanoelectronics. In article number 1800360, Junsuk Rho and co‐workers develop a programmable metallization memristor with a simple Ag/phase change material/Pt structure using an alloy compound of Ge, Sb, Te (GST). The performance of the memory device is improved by a facile nitrogen‐dopant method. Reliable and reproducible uniform switching characteristics are reported by the nitrogen‐doped GST device.
