| Popis: | International audience; WO 3 nanostructures have been synthesized on Au(111) through solution processing. Three types of structures have been obtained, reticulated polymeric structures, two dimensional WO 3 (111) and three-dimensional islands. Their electronic properties have been probed by scanning tunneling spectroscopy. The reticulated structure has a featureless spectrum. WO 3 (111) shows n-type semiconducting properties with resonances corresponding to surface states arising from W 5d states. Those oxyde nanostructures are efficiently decoupling the electronic states of molecular adsorbates from the metal substrate. |
