In this paper, a gold nano-dot (Au-ND) is successfully prepared on a silicon tip apex for scanning Kelvin probe microscopy (SKPM) applications. An extra facile localized fluoride assisted Galvanic replacement reaction (LFAGRR) is proposed to replace the silicon (Si) atoms at the tip apex with Au one...
