“…Furthermore, it can also be clearly seen that Ti L 3 and L 2 edges further split into t 2g (A1 and C1) and e g (B1 and D1) states due to crystal field effect. Compared with the Ti L 2,3 spectra of TiO 2 from the reference [42], the secondary peaks A1 and C1 around the main peaks in all samples are due to the oxidation of the TiN layer. However, the intensities of A1 and C1 relative to those of B1 and D1 in the Si/TiN/ZrO 2 sample is higher than that in the other two samples.…”

Interface behavior plays an important role in multilayer structure. The deep understanding of interface diffusion and reaction is necessary to improve the performance of device with multilayer structure. In the present work, we perform a detailed systematic study on interdiffusion and interaction between the TiN and ZrO x N y layers in the TiN/ZrO x N y bilayer system. A series of TiN/ZrO x N y bilayers with reverse deposition orders or with varied composition have been prepared by radio-frequency reactive magnetron sputtering. Synchrotron radiation x-ray absorption spectroscopy (XAS) and time of flight secondary ion mass spectrometry (ToF-SIMS) are both used to understand well interface diffusion behavior. The XAS results indicate that interaction and interdiffusion extent between TiN and ZrO 2

“…There are different mechanisms for ferromagnetic coupling in the literature for TiO 2 -based DMS, such as carrier-mediated exchange 48 and bound magnetic polaron (BMP) model. 49 Tian et al 36 speculated that the ferromagnetic coupling between V ions mediated by oxygen vacancies at interfaces may account for the observed room temperature ferromagnetism in V-doped TiO 2 nanoparticles. Hong et al 50 reported the large value of magnetic moment of 4.2 μ B /V for the V:TiO 2 films and suggested that the room temperature ferromagnetism did not come from V clusters but from V-doped TiO 2 matrix.…”

“…The second broad resonance (535 -548 eV) exhibits larger dispersion effects and is more sensitive to long-range order [15]. Feature J is attributed to the transition from O1s to the O2p antibonding state [13,16] whereas features K and L are primarily ascribed to O2p character hybridized with Ti4s and 4p states (3a1g and 4t1u) [17].…”
