The In2O3 films (Figure 1a,d) have a uniform thickness and are characterized by a more dense packing of the grains as compared to the ZnO deposit, which consists of plate-like crystallites with approximately 100

Inside the bright stripes the density of titanium atoms is higher than in the trenches, which is a result of the lattice mismatch between the titanium oxide film and the

In order to produce a consistent and reproducible titanium oxide surface layer, four different chemical treatments were tested

• XPS, the exposure of titanium and titanium oxide surfaces to air resulted in a thin adherent layer of organic contaminants. The presence of such an organic contaminant layer influences the optical dispersion function of the titanium films. These ill-defined optical parameters of the titanium

Scientifically, it is also interesting to learn whether the formation of both a sub-oxide and an ordered phase, as seen in the Magnéli phase observations, are necessary preconditions to allow resistance switching in the titanium oxide system

• required an initial electroforming step which creates a channel of reduced titanium oxide [26], increasing the conductivity and allowing subsequent bipolar resistance switching to take place. As shown in Figure 1a, the initial high-resistance state (“Virgin”) can never be attained and thus the

The NEXAFS therefore indicates a mixed-valence composition including both Ti3+ and Ti4+, and matches well the spectrum observed in reduced titanium oxide layers [36][37][38]. It is additionally worth noting that the spectrum observed in the ON and OFF
