Annotation	The surface work-function (WF) of a (semi-)conductor is the key parameter which determines the amount of electrons that can be emitted from its surface and thus it defines the electronic parameters of the electrical junctions which, in turn, define the final characteristics of various electronic devices. One of the possible ways to tune the noble metal WF is the use of Self-Assembled Monolayers (SAMs) of oriented dipoles. SAMs of carboranes with exceptionally high thermal stability represent promising candidates and it was shown that silver work-function can be tuned very precisely over a range of 1 eV. In this work we show the formation of SAMs of carborane-thiols molecules on the smooth gold surfaces of well-defined gold single-crystals using ambient conditions AFM. The detailed comparison of high-resolution topography maps obtained under different deposition conditions will be presented and their physisorption and chemisorption will be discussed.
