Surface morphologies of SnO 2 ( 110 )

Tuning surface properties of SnO2(101) by reduction

“…However, the (1 1 0) surface is less well-defined compared to the (1 0 1) surface because the (1 1 0) surface forms complex surface reconstructions upon surface reduction [4]. Therefore the (1 0 1) surface may be the better suited surface for fundamental studies of site requirements for surface reactions on oxide surfaces.…”

“…ion sputtering and annealing under ultrahigh vacuum (UHV) conditions, results in reduced SnO 2 surfaces [3,4]. In order to produce a stoichiometric surface the samples have to be exposed to high O 2 or NO 2 pressures, or treated by an oxygen plasma [3].…”

Surface Science Studies of Gas Sensing Materials: SnO2

“…The “1×1”structure turns out to be a disordered surface with the 1×1 LEED spots most likely originating from the subsurface region. [29] The 1×2 structure has large flat terraces; however, the surface is quite defective. In another study, using photoelectron spectroscopy, in the Cooper minimum for Sn, Themlin et al [30] demonstrated that the Sn/O ratio is high after Ar + -sputtering and that even after annealing to 1000 K the bulk stoichiometry is not recovered at the surface.…”

Pure and cobalt-doped SnO2(101) films grown by molecular beam epitaxy on Al2O3

“…One reason for the lack of experimental studies is that only a few and mostly small single crystals exist. Most existing surface science studies on SnO 2 were focused on the (110) surface [1]. The (110) surface is the surface that exhibits the lowest surface energy [2] of the stoichiometric low index SnO 2 surfaces and is the dominant bulk termination for single crystals grown by vapor phase transport techniques [3].…”
