Growth of Pt clusters electrodeposited onto boron-doped diamond films

The growth of Pt particles electrochemically deposited onto boron-doped diamond thin films supported by silicon wafers has been studied by cyclic voltammetry and by atomic force microscopy. On a small number of diamond sites the initially electrodeposited Pt particles present a fast growth, which ca...

Description
Summary:The growth of Pt particles electrochemically deposited onto boron-doped diamond thin films supported by silicon wafers has been studied by cyclic voltammetry and by atomic force microscopy. On a small number of diamond sites the initially electrodeposited Pt particles present a fast growth, which can be attributed to a better electrical conductivity resulting from a higher local concentration of boron used in the boron-doped diamond films as doping centres.
