“…20,21 Alternatively, phosphonate molecules have been proposed to form self-assembled monolayers (SAMs) on hydroxylated and oxide surfaces. 22−25 Surface functionalization with SAMs is widely used in applications, ranging from work function changes of transparent conductive ZnO electrodes 26,27 to organic thin film transistors, 28 and has recently been extended to lubrication, 29,30 photovoltaics, 31 sensors, 32 and even bioactive coatings. 33,34 Thus, a broad field of applications is addressed.…”

Efficient control of interface chemistry can lead to better tunability of electronic properties along the interface, which is at the central focus for many scientific and technological applications. Recently self-assembled organophosphonate monolayers (SAMs) on various oxide surfaces found increasing attention in electrical and sensor applications due to their high stability and reproducibility. Here we demonstrate a novel, near-UV-initiated direct modification of H-terminated silicon surfaces with different alkylphosphonic acids. This grafting produces densely packed organic monolayers within an hour and can be performed under catalyst-free conditions. The SAMs show high hydrolytic stability at pH 3 and 11.

“…Another positive effect of occurrence of energetically advantageous Si-O bonds is creation of perfluoroalkylsilanes network consisting of Si-O-Si linkages during the modification process. Additionally, surface modification by perfluoroalkylsilanes guarantees more satisfied physical-chemical properties than in the case of compounds that do not contain silicon in their structure [24,25,27].…”

The presented article shows the influence of concentration of perfluoroalkylsilanes in solutions on tribological properties of self-assembled monolayers (SAMs) deposited on three surfaces with different silicon content in the millinewton load range. The SAMs were created using the liquid phase deposition (LPD) method with 1H, 1H, 2H, 2H-perfluorodecyltrichlorosilane (FDTS) and (3, 3, 3-trifluoropropyl) trichlorosilane (FPTS) solutions, for which viscosity and surface tension were estimated. Deposited layers were analyzed in terms of thickness, coverage, wettability, structure and coefficient of friction. The obtained results demonstrated that SAMs created on the silicon-incorporated diamond-like carbon (Si-DLC) coatings possess the best microtribological properties. Systems composed of perfluoroalkylsilane SAM structures deposited on Si-DLC coatings are highly promising candidates as material for microelectromechanical applications.
