Electrostatic assembly of alumina nanoparticles on nanocrystalline diamond films
Original language description
We apply atomic force microscope for local electrostatic charging of oxygen-terminated nanocrystalline diamond (NCD) thin films deposited on silicon, to induce electrostatically driven self-assembly of colloidal alumina nanoparticles into micro-patterns.The NCD films have sub-100 nm thickness and 60% relative sp2 phase content. We characterize charge contrast and stability in air, fluorocarbon oil and water by Kelvin force microscopy. We discuss factors influencing the charging process and demonstratethat the contrast of more than 1 V is needed to induce selfassembly of the nanoparticles via coulombic and polarization forces.
