2D Materials Can Now be Controlled with Redox Reactions
Posted by MSE Supplies Admin on
Researchers at the Pohang University of Science & Technology (POSTECH) Department of Chemistry have discovered that redox reactions can be used to control the properties of two-dimensional (2D) materials. Redox reactions between water and oxygen molecules in the air drive an electrochemical reaction within 2D materials that dopes them with charges from the surrounding environment. For this experiment, graphene and tungsten disulfide were analyzed, using Raman spectroscopy and photoluminescence imaging respectively, to demonstrate this phenomenon on the nanoscale. Key material properties such as the magnetic, optical, and electrical nature of the materials were all controllable via redox manipulation. Now that...

3D ReRAM, a promising candidate for high density high speed non-volatile memory (NVM)
Posted by MSE Supplies on
With the progress in network virtualization, efficient data center operation raises the high demand for faster memory technology with higher density. 3D Resistance RAM (ReRAM) arrays, a likely candidate for replacing NAND Flash, have the potential for the next generation high density non-volatile memory (NVM). Crossbar, a six year-old start-up with ReRAM expertise, recently announced embedded 40nm ReRAM with CMOS process sampling from SMIC (Semiconductor Manufacturing International Corp. Shanghai, China). Crossbar says the technology will scale to 16nm and 10nm. Comparing to NAND, the 3D ReRAM technology can deliver 20X faster write/read performance, 20x lower power consumption and 10x endurance...
