Surface potential of diamond and gold nanoparticles can be locally switched by surrounding materials or applied voltage
Original language description
Properties of nanoparticles in contact with other surfaces are crucial for various applications. Here, we show that electrical potential of individual nanoparticles or their aggregates (sizes 5?50 nm) can be locally switched between negative and positivevia work functions of surrounding materials (Si, Au, and Pt). We employed novel methodology of Kelvin probe force microscopy (KPFM) to characterize surface potentials of hydrogenated, thermally oxidized, and partially graphitized detonation diamond nanoparticles (5 nm), as well as gold nanoparticles (20 nm) deposited on the substrates (Si, Au) from colloidal dispersions in water or methanol.
