首次用原子探针层析法直接观察到了含氘溶质原子的Fe/V多层膜的氘死层。死层的厚度测量为0.4- 0.5nm。死层可以与化学混合层区分开来。结果表明，死层效应发生，甚至附近的混合层的界面，支持的解释，死层效应不能解释仅仅通过电子电荷转移，但也涉及到刚性的调制。(C)2012 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
The first direct observation, by atom probe tomography, of a deuterium dead layer is reported for Fe/V multilayered film loaded with D solute atoms. The thickness of the dead layers was measured to be 0.4-0.5 nm. The dead layers could be distinguished from chemically intermixed layers. The results suggest that the dead layer effect occurs even near the interface of the mixing layers, supporting an interpretation that the dead layer effect cannot be explained solely by electronic charge transfer but also involves a modulation of rigidity.
