Scanning tunnelling microscopy observations resolve the structure and dynamics of metallic glass Cu100-xHfx films and demonstrate scanning tunnelling microscopy control of aging at a metallic glass surface. Surface clusters exhibit heterogeneous hopping dynamics. Low Hf concentration films feature an aged surface of larger, slower clusters. Argon ion-sputtering destroys the aged configuration, yielding a surface in constant fluctuation. Scanning tunnelling microscopy can locally restore the relaxed state, allowing for nanoscale lithographic definition of aged sections.
扫描隧道显微镜观察解析了金属玻璃Cu100-xHfx薄膜的结构和动力学，并展示了在金属玻璃表面通过扫描隧道显微镜控制老化过程。表面团簇呈现出非均匀的跳跃动力学。低铪浓度薄膜的特征是具有较大、运动较慢团簇的老化表面。氩离子溅射破坏了老化构型，产生了不断波动的表面。扫描隧道显微镜可以局部恢复松弛状态，从而实现对老化区域的纳米级光刻定义。
