Morphology and stability of Au nanoclusters in HOPG nanopits of well-defined depth

Wolfgang Harbich, Michael Hugentobler, Simon Bonanni

Gold nanoparticles with a diameter comprised between 4 and 6 nm are stabilized in nanosized pits of well defined depth in highly oriented pyrolytic graphite (HOPG). These pits are produced by creation of artificial defects, followed by etching under a cont ...

Development and characterization of EIS structures based on SiO2 micropillars and pores before and after their functionalization with phosphonate films

Anna Fontcuberta i Morral, Anna Dalmau Mallorquí

In this work electrolyte insulator semiconductor (EIS) structures based on lithographically fabricated Si SiO2 micropillars and pores are studied. The samples are characterized by means of impedance spectroscopy (IS) and they are compared to samples with a ...

Electrochemical properties of gold nanoparticles assembly at polarised liquid|liquid interfaces

Hubert Girault, Mohamad Hojeij, Nathalie Younan, Lydie Ribeaucourt

Capacitance measurements of a polarised liquid|liquid interface show that the capacitance of the interface increases in the presence of an adsorbed monolayer of citrate-coated gold nanoparticles. This unusual observation can be explained by an increase of ...
