There is strong interest in lithium imaging, particularly because of its significance in battery materials. However, light atoms only scatter electrons weakly and atomic resolution direct imaging of lithium has proven difficult. This paper explores theoretically the conditions under which lithium columns can be expected to be directly visible using annular bright field scanning transmission electron microscopy. A detailed discussion is given of the controllable parameters and the conditions most favourable for lithium imaging.
人们对锂成像非常感兴趣,特别是因为它在电池材料中的重要性。然而,轻原子只微弱地散射电子,直接对锂进行原子分辨率成像一直很困难。本文从理论上探讨了使用环形明场扫描透射电子显微镜直接观察锂柱的条件。详细讨论了可控制参数和最有利于锂成像的条件。
