The use of nanoparticle materials in the manufacture of electronic polymer memory devices is on the rise. Organic memory devices are fabricated by depositing a blend of organic polymer, small organic molecules, and nanoparticles between two metal electrodes. The primary aim is to produce devices that exhibit two distinct electrical conductance states when control voltages are applied. By retaining the states when power is removed can be viewed as the realization of nonvolatile memory. In this letter, an attempt is made to further understand the conundrums that scholars in this field are currently facing, with questions about the nanoparticle charging mechanism being investigated.
