Dielectric properties of (multilevel) switching devices based on ultrathin organic films

摘要: Abstract Dielectric properties of an organic material, which shows conductance switching with associated memory phenomenon, have been studied. The devices modeled as a parallel combination resistor and capacitor. During switching, devices’ resistive capacitive found to change. Multilevel conductivity, is due different density high-conducting reduced molecules in the devices, has also manifested dielectric measurements. We could induce (‘write’) low-conducting state three states probe (‘read’) them by measuring frequency dependence impedance characteristics without any dc bias for multilevel read-only random access applications.
