Hafnium X-ray photoelectron spectra, hafnium electron configuration, and other elemental information. If analyzing nitrided hafnium oxide or silicate, collect entire Hf4p region (up to 490eV), making sure both Hf4p 3/2 and Hf4p 1/2 components are acquired.

In this work, we compare the resistive switching characteristics between Ti/ZrOX/TiN and Ti/ZrOX/HfAlOX/TiN. The bilayer structure of the ZrOX-based device enables power consumption reduction owing...

在XPS测试谱图中，对于带 2p、3d、4f标识的元素，比如S2p、Ba3d、Pb4f等元素；由于自旋劈裂效应，当这些元素存在一种化学态时，就会劈裂成两个不同属性的峰，…

X-ray photoelectron spectroscopy (XPS) and thermodynamic data indicated that Acetone-Methanol-Isopropanol (AMI) pre-clean process on InP substrate before Sulfur treatment helps the formation of...

Hafnium is a transition metal with a valance of (IV) and forms a single oxide HfO2. The intensity ratio of the Hf 4f 7/2 and Hf 4f 5/2 peaks are constrained to 4:3. The two peaks are separated by a value of D= 1.71 eV [1]. The Hf 4f 7/2 binding energy for the metal is found at 14.3 eV and is fit with an asymmetric peak-shape.

HfO2 thin film is deposited on p-Si substrates by RF magnetron sputtering apparatus and annealed at 750 °C for 10 min with O2 atmosphere. Spectral analysis shows that HfO2 thin films have good...

X 射线光电子能谱 ( X-ray photoecectron spectroscopy， XPS) 技术是一种通过一束入射到样品表面3~10nm 深度的光子束，检测材料表面信息的无损测量技术。 XPS 技术能很好地使样品保持其原有的结构信息，可用于定性…

最近做XPS测试，检测出来了Hf4f峰，峰形和位置跟文献上的对的上，拟合的也很好（如图），按文献上的说法这是意味着形成了Hf-O键，但是老师看让我把Hf元素的价态分析出来，我就犯难了，求助各位大神，如何用XPS确定元素的价态？

XPS Spectra Hafnium (Hf) Compounds The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra. Atom% values from surveys are based on sample, as received, and Scofield cross-sections. Atom% values are corrected for IMFP and PE.

2022年5月6日 · The HAXPES spectra of HfO 2 obtained using monochromatic Cr Kα radiation at 5414.8 eV include two survey scans (Al Kα and Cr Kα) and high-resolution spectra of Hf 3s, Hf 3p 3/2, Hf 3d 5/2, Hf 4p 3/2, Hf 4d, Hf 4f, Hf 4s, and O 1s.
