Electrical bistability in electrostatic assemblies of CdSe nanoparticles

Article Abstract:

A study investigates electrical bistability in electrostatic assembly of CdSe nanoparticles by obtaining thin films of the nanoparticles via layer-by-layer electrostatic assembly technique, which provides a nanoscale control to tune the thickness. Devices based on such thin films exhibit electrical bistability along with memory phenomenon, in which the bistability is due to charge confinement in the nanoparticles.

Electrical Bistability and memory phenomenon in carbon nanotube-conjugated polymer matrixes

Article Abstract:

A study was carried out to observe electrical bistablility and large conductance switching in functionalized carbon nanotube (CNT)-conjugated polymer composites at room temperature. In the bistable devices, the active layer retained its high-conducting state until a reverse voltage erased it.

Memory-switching phenomenon in acceptor-rich organic molecules: Impedance spectroscopic studies

Article Abstract:

A study of the memory-switching phenomena in terms of impedance spectroscopy in series xanthene-class fluorescein molecules is presented. It is concluded that conductance switching is associated with dielectric changes of the material.
