The particle deposition was driven using a high electric field - the key aspect was that the enhanced electric field surrounding the nanowire tips attracted particles to the top of the nanowire array.

The simultaneous measurements of the magnetic hysteresis loops and thickness-dependent electric conductance were performed in-situ during deposition process.

Influence of the cathode electric current density, the agitating methods, the concentration and size of diamond powder and the placing methods of substrate on the deposition effect are discussed.
