Strain effects of Ti 3d subband splitting and peak energy shift. (a) Subband splitting of Ti 3d state at AlO/STO interfaces under compressive strain ~−1.16 % (by NdGaO3 substrate, NGO), without external strain, and tensile strain ~+1.29 % (by TbScO3 substrate, TSO). (b) Relative peak energy shift (with unpolarized X-rays) of Ti L2,3-band in AlO/STO interfaces under compressive strain ~−1.16 % (negative energy direction) and tensile strain ~+1.29 % (positive energy direction).
