Fig. 2: EELS and XAS of C30/Tn heterostructures.
From: Three dimensional band-filling control of complex oxides triggered by interfacial electron transfer
a The Co L-edge EELS spectra of C30/T15 at different positions from STO/LCO to the LCO/LTO interface. The bottom curve is from the STO substrate/LCO interface, and the uppermost curve is from the LCO/LTO interface. b The corresponding Co L3,2 intensity ratio. The LCO/LTO interface sets for zero. The averaged c Co L-edge and d O K-edge EELS spectra of C30/T15 and C30/T0. The shadow area in d indicates the distinct difference in the pre-peak feature. The spectra were averaged from the line scan in the 30u.c. LCO block. e Co L-edge XAS spectra of the C30/T15 and C30/T0 samples. f The Ti L-edge XAS spectra of the STO substrate, C30/T15, and 100-nm YTiO3 film from ref. 10.
