• molecules into the Sn-down conformation was observed either after sample annealing at 200 °C or as a result of tip-induced manipulation. Room-temperature measurements conducted for a coverage of close to a monolayer showed no tendency for molecular arrangement. Keywords: rutile (110) surface; scanning

• assume that the shape asymmetry of SnPc may also appear as a result of the presence of the surrounding molecules, or it can arise from the corrugated nature of the rutile (110) surface including its defects. To confirm the identification of Sn-up and Sn-down geometries, we performed DFT calculations. A

• freely between both geometries. On Ag(111), the free switching appeared in subsequent layers. This mainly suggests that the surface influences the switching process and indicates that the Sn-down Pc position is preferable. Here, tip-induced irreversible switching was observed on a rutile (110) surface

• investigation of molecular adsorption is titanium dioxide [11][12]. The most stable and the most studied face of TiO2 is the rutile (110) surface. In the context of adsorption studies, it is important to note that the (110) face of rutile usually contains numerous oxygen vacancies, often filled with hydroxy

• five (and even higher) times the substrate periodicity [1][5]. For a single ML coverage, a c(6 × 2) honeycomb lattice was observed on the rutile (110) surface [5]. Additional structures, perpendicular to the primary rows (namely, along the direction) and forming a bi-dimensional network, have been

• areas free of calcium are visible. We have reported that in atomically resolved images of the rutile (110) surface in water, a 2× periodicity is measured along the [001] direction, suggesting the presence of an adsorbed overlayer (very likely water molecules) [18]. In the present experiment, the quality
