Fluorinated SAMs on Si(001) surface: Surface electronic properties and structural aspects

GRAPHICAL ABSTRACT

Abstract

Due to their insulating properties, small organic molecules deposited on the silicon surfaces, can be used as organic transistors. Since the molecular resistance is known to increase with increasing content of electron withdrawing groups, the self-assembled monolayers (SAMs) with the fluorocarbon moieties have been used to study the electronic properties of underlying solid substrate. Moreover, fluorinated SAMs may undergo charge transfer with leading materials designed for organic electronic devices. This minireview focuses on the structure of underlying silicon surface after wet-chemical routes towards the formation of silicon–organic monolayers and describes ways of potential changes in the electronic properties of covered silicon surface.
