  • Title: Transparent and flexible graphene charge-trap memory.
    Author: Kim SM, Song EB, Lee S, Zhu J, Seo DH, Mecklenburg M, Seo S, Wang KL.
    Journal: ACS Nano; 2012 Sep 25; 6(9):7879-84. PubMed ID: 22889250.
    Abstract:
    A transparent and flexible graphene charge-trap memory (GCTM) composed of a single-layer graphene channel and a 3-dimensional gate stack was fabricated on a polyethylene naphtalate substrate below eutectic temperatures (~110 °C). The GCTM exhibits memory functionality of ~8.6 V memory window and 30% data retention per 10 years, while maintaining ~80% of transparency in the visible wavelength. Under both tensile and compressive stress, the GCTM shows minimal effect on the program/erase states and the on-state current. This can be utilized for transparent and flexible electronics that require integration of logic, memory, and display on a single substrate with high transparency and endurance under flex.
