The ferromagnetically coupled ferroelectric domain walls (DWs), which may be more conductive, in multiferroic material BiFeO3 (BFO), make it possible to realize intrinsic multiferroelectricity in single phase material and open a chance for combining spintronics and ferroelectricity in multifer-roic systems.[1] From the aspect of conductivity, the conductive DWs will influence the macroscopic transport...
This paper presents synthesis and characterization of conducting polypyrrole-multi-walled carbon nanotube films co-depositing onto nickel electrode substrate. The electrochemical polymerization of pyrrole is performed in 100ml aqueous solution containing 0.2M pyrrole, 0.05M AOT and 0.01g multiwalled carbon nanotubes using three-electrode system. The SEM and cyclic voltammetry analysis show that the...
We show that optic ally-gated carbon nanotube field effect transistors can be used as 2-terminal like devices with light sensitivity and memory capabilities. In particular, their channel resistivity can be adjusted precisely, within a large range and memorized. These devices can thus be used as synapses in neural network type of circuits. We demonstrate experimentally these properties, build a device...
