本文中,当SrRuO3薄膜卷曲成管状结构后,内/外两层分别受到压应变和拉应变,通过磁性M-H曲线中饱和磁矩的变化(图 4c)以及XPS中结合能的峰位偏移(图 4d)证实了Ru4+的电子结构从t2g(3↑, 1↓) 转变为t2g(3↑)eg(1↑),eg电子数为1时,有利于增强电化学析氧反应效率。 图4 刚性和柔性SrRuO3的磁性、XPS测...
Further analysis of XPS data has confirmed that the presence of a valence band offset (VBO) and the value of VBO is found to be + 0.02 eV and – 0.38 eV for the bilayers of STO/LaNiO3/SrRuO3 (BL-1) and STO/SrRuO3/LaNiO3 (BL-2), respectively. The distinct signs of VBO have ...

sion spectroscopy (XPS) to identify how such correla- tions change within the ruthenate family, and Toyota et al. 18 use photemission spectroscopy (PES) to detail the metal-insulator transition in SrRuO 3 as a function of film thickness concomitant with the onset of mag- ...
x-ray photoelectron spectroscopy (XPS)chemical phase separationWe explore the crystal structure, electrical resistivity and magnetic behavior of the compositional series (SrRuO3)(1-x) (GdCrO3)(x) (where 0 <= x <= 1), which resides between orthorhombic ferromagnetic (FM) metal SrRuO3 (T-C =...
The X-ray photoelectron spectroscopy (XPS) results show that oxygen vacancies are accumulated at the PZT/SRO interfaces, which can reduce the depolarization fields and the leakage current. The results demonstrate that the thickness of metallic conducive oxide in the ferroelectric/metallic superlattices ...
valence bandsX-ray photoelectron spectra/ metal-insulator transitionvalence bandXPS data and electrical transport data show that doping of Mn in metallic SrRuO 3 induces mixed ionic pair Ru(IV)/Ru(V)Mn(III)/Mn(IV) and the system undergoes a transition from metal to insulator at the critical ...
X-ray photoemission spectroscopy (XPS) was also carried out to analyze the SRO thin films, as shown in Figure S2. The peaks at the binding energies 464.3, 531.7, and 529.2 eV correspond to the Ru 3p3/2 defect-like oxygen vacancy and SRO (O 1s) orbitals, respectively. Technically, it ...
