XPS 表面成分分析，先定义目标元素、化学态与取样历史。XPS surface analysis starts with target elements, chemical states and sample history.

XPS 适合分析表面数纳米范围内的元素组成与化学态，也可配合离子溅射做深度趋势。可靠结果需要区分全谱、窄谱、峰拟合和深度剖析，并记录清洗、空气暴露与荷电校正条件。XPS probes near-surface elemental composition and chemical states; survey, high-resolution, fitting and sputter-depth work require different plans and controls.

01

适合什么需求Good For

薄膜与表面改性后的元素组成、氧化态和键合状态；污染、残留和界面趋势判断；沉积、刻蚀、清洗或退火前后对照。Elemental composition, oxidation and bonding states, contamination, residues and before/after process comparison.

02

需要准备什么Prepare First

样品材料与尺寸、制备和暴露历史、目标元素及预期化学态、全谱/窄谱范围、测点与对照组、是否绝缘、是否需要峰拟合或深度剖析。Sample, process and exposure history, target elements and states, spectra, point map, controls, charging and depth-profile needs.

03

常见风险Common Risks

空气污染覆盖真实表面、绝缘样品荷电漂移、峰拟合约束不透明、检测限不足、离子溅射改变价态或优先溅射，以及把表面结果误当成体相组成。Adventitious contamination, charging, opaque fitting constraints, detection limits, sputter damage and confusing surface with bulk composition.

推荐下一步Next Step

把“测一下 XPS”转换成谱图矩阵、对照组与拟合交付表。Translate an XPS request into a spectra matrix, controls and fit-delivery checklist.

请提交样品材料、制备和储存方式、关注元素与化学态、测点示意、对照组、是否需要深度剖析，以及原始谱、拟合参数和定量表的交付要求。微纳Hub 会先判断 XPS 是否需要与 AES、ToF-SIMS、EDS 或截面分析组合。Share the sample history, target elements and states, locations, controls, depth needs and raw-data requirements so XPS can be compared with AES, ToF-SIMS, EDS or cross-section analysis.
