Chains of semiconductor nanorods linked by Au particles represent an ideal model system in this respect, because the metal\u2013semiconductor interface is an intrinsic feature of the nanosystem and does not manifest solely as the contact to the macroscopic external electrodes. Here we investigate charge transport mechanisms in all-inorganic hybrid metal\u2013semiconductor networks fabricated via self-assembly in solution, in which CdSe nanorods were linked to each other by Au nanoparticles. Thermal annealing of our devices changed the morphology of the networks and resulted in the removal of small Au domains that were present on the lateral nanorod facets, and in ripening of the Au nanoparticles in the nanorod junctions with more homogeneous metal-semiconductor interfaces. In such thermally annealed devices the voltage dependence of the current at room temperature can be well described by a Schottky barrier lowering at a metal semiconductor contact under reverse bias, if the spherical shape of the gold nanoparticles is considered. In this case the natural logarithm of the current does not follow the square-root dependence of the voltage as in the bulk, but that of V2\/3. From our fitting with this model we extract the effective permittivity that agrees well with theoretical predictions for the permittivity near the surface of CdSe nanorods. Furthermore, the annealing improved the network conductance at cryogenic temperatures, which could be related to the reduction of the number of trap states.<\/jats:p>","DOI":"10.1021\/nn3006625","type":"journal-article","created":{"date-parts":[[2012,3,9]],"date-time":"2012-03-09T18:57:31Z","timestamp":1331319451000},"page":"2940-2947","source":"Crossref","is-referenced-by-count":46,"title":["Charge Transport in Nanoscale \u201cAll-Inorganic\u201d Networks of Semiconductor Nanorods Linked by Metal Domains"],"prefix":"10.1021","volume":"6","author":[{"given":"Romain","family":"Lavieville","sequence":"first","affiliation":[{"name":"Istituto Italiano di Tecnologia (IIT) , Via Morego 30, 16163 Genova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Zhang","sequence":"additional","affiliation":[{"name":"Istituto Italiano di Tecnologia (IIT) , Via Morego 30, 16163 Genova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alberto","family":"Casu","sequence":"additional","affiliation":[{"name":"Istituto Italiano di Tecnologia (IIT) , Via Morego 30, 16163 Genova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessandro","family":"Genovese","sequence":"additional","affiliation":[{"name":"Istituto Italiano di Tecnologia (IIT) , Via Morego 30, 16163 Genova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liberato","family":"Manna","sequence":"additional","affiliation":[{"name":"Istituto Italiano di Tecnologia (IIT) , Via Morego 30, 16163 Genova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Enzo","family":"Di Fabrizio","sequence":"additional","affiliation":[{"name":"Istituto Italiano di Tecnologia (IIT) , Via Morego 30, 16163 Genova, Italy"},{"name":"University of Magna Graecia Campus S.
