From: Growing a LaAlO3/SrTiO3 heterostructure on Ca2Nb3O10 nanosheets
ARRES maps from different samples. (a) LaAlO3/SrTiO3 on Ca2Nb3O10 nanosheets (sample C); (b) LaAlO3 on SrTiO3 substrate (sample D). On both samples 5 unit cells of LaAlO3 were grown, both images are on the same energy scale. (c) LaAlO3 on SrTiO3 substrate, conducting interface (sample S1-C from ref. 14); (d) LaAlO3 on SrTiO3 substrate, non-conducting interface (sample S2-I from ref. 14). On both samples 4 unit cells of LaAlO3 were grown, both images are on the same energy scale. (c,d) were taken from16.
