摘要：
High resolution electron microscopy has been used to monitor the changes at the surface of Sr3La2Ti2O10 caused by electron beam irradiation. Initially, the surface is covered by a layer of amorphous metal oxide a few tens of angstrom units thick. Crystallisation occurs within this layer and continues with further exposure to the electron beam. Computer modelling and image simulations have shown that the new surface structure is that of perovskite, which possesses corner-linked TiO6 octahedra in common with the bulk compound.
