Microcontact Printing of Ultrahigh Density Gold Nanoparticle Monolayer for Flexible Flash Memories

Abstract
A uniform monolayer of alkanethiol‐protected gold nanoparticle arrays with ultrahigh density have been used as microcontact‐printable charge‐trapping layers for the application in flexible flash memories. The new devices are compared to two reference devices with a floating gate created by thermal evaporation and electrostatic self‐assembly, and show a large memory window, long retention times and good endurance properties.
