Water adsorption on SrTiO3(001): II. Water, water, everywhere

Modification of SrTiO3 surface by nitrogen ion bombardment for enhanced photocatalysis

“…Some of the surface defects could act as trapping sites for photo-generated carriers, preventing them from rapid recombination [28]. They would also form extra dissociative adsorption sites for water and organic molecules as oxygen-vacancy defects for instance [29,30], which contribute to photocatalysis as well. Fig.…”

Transition from Order to Configurational Disorder for Surface Reconstructions onSrTiO3(111)

“…The (001) surface is dominated by arrangements of edge-or corner-shared TiO 5 [] units to yield a valencecompensated structure, exactly which are formed depending heavily upon the kinetics during sample preparation [36,37] Since the different structures all lie on essentially a straight line in the enthalpy-coverage convex hull of Fig. 4, for any specific surface excess of TiO 2 there will be many different mixtures of structures with nearly degenerate enthalpies.…”

Lanthanum aluminate (110) 3 × 1 surface reconstruction

“…It is appropriate to make a few comments about how the reconstruction forms, using knowledge from the STO surfaces [37,38] as well as the MgO and NiO (111) surfaces [39,40]. It is reasonable that the initial ion-beam preparation of ABO 3 perovskites leads to a slightly A deficient surface with a slight B excess.…”
