Ga2p or Ga3d typically used. Using the Ga2p peak will give better depth resolution for sputter profiling. Ga3d electrons have higher kinetic energy and therefore have a deeper sampling depth compared to the low kinetic energy Ga2p electrons. The Ga3d region is sometimes more informative for chemical analysis. Interpretation of XPS spectra.

XPS 光谱解读. Ga2p 区域具有明显分离的自旋轨道分裂峰 (Δ=26.9 eV，强度比=0.491)。 单质镓的 Ga2p 峰不对称，镓化合物的 Ga2p 谱峰对称。 通常仅对 Ga2p 区域的 Ga2p3/2 谱峰进行拟合和定量。 可以在自旋轨道分裂峰 (1130 eV) 之间观察到能量损失特征峰。

X 射线光电子能谱 (XPS) 分析表明 Ga 2p 双峰的结合能 (BE) 即 Ga 2p3/2 和 Ga 2p1/2 峰分别位于 1118.0 和 1145.0 eV，表征镓的最高沉积薄膜中的化学氧化态（Ga3+）。O 1s的核心能级XPS光谱表明峰集中在BE~531 eV，这也是Ga2O3相中Ga-O键的特征。

XPS Spectra Gallium (Ga) 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.

Collect principal Ga (2p) peak as well as Ga (3d). Long time exposures (high dose) to X-rays can degrade various polymers, catalysts, high oxidation state compounds During XPS analysis, water or solvents can be lost due to high vacuum or irradiation with X-rays or Electron flood gun

This work shows results from an extensive analysis of the Ga 3d5/2, Ga 2p3/2 and Ga L3M45M5 spectra of a broad series of Ga compounds. Binding energy positions, Auger parameters and chemical state (Wagner) plots are then used to understand the trends found for the various series of related compounds and to understand the chemistry of newly ...
