Abstract: | We report on the fabrication of micrometric regular metallic arrays obtained
by using, as a template, a polymeric membrane with regular pores. The
membranes were prepared by embedding hydrophobized silica colloids into a
polymer layer and subsequently removing them. We have investigated the
electronic transport properties of the metallic arrays as a function of the
applied electric field and temperature. Simple current voltage (IV)
characteristics present a strong switching behavior with ION/IOFF
ratios up to 104. Different temperature dependences of the resistance
in the different ranges of the applied electric field have been observed.
Finally, the performances of a field effect device (FET), with the
conducting channel and insulating layer consisting of a Gold dot array and a
STO substrate, respectively, have been investigated. The channel resistivity
has been modified at least of two orders of magnitude and a mobility of
about 2 cm2/V*s has been extracted by the analysis of the FET transfer
curve. |
