原子在岛的角位置处和周围的势能控制着致密岛的形状和枝晶生长的行为，因此它是理解薄膜外延的最重要的参数之一。用场离子显微镜详细测定了Ir（111）岛角处及附近Ir原子的势能。基于所测量的势能，可以在原子水平上理解许多岛的形状和生长行为。
The potential energy of an atom at and around the corner site of an island controls the shape of compact islands and the behavior in dendritic growth, thus it is one of the most important parameters in understanding thin film epitaxy. Using the field ion microscope we determine in details the potential energy of an Ir atom at and around the corner of the Ir(111) island. Based on the measured potential energies, many island shape and growth behavior can be understood at the atomic level.
