高阻抗扫描隧道显微镜已用于对 Au(111) 上并五苯薄膜的生长进行成像。这些薄膜中的并五苯分子形成共面、π堆积晶相，其分子平面平行于表面，而不是块状固体中的人字形结构。该结晶相的生长归因于密堆积结晶单层的形成，该单层结晶单层为π堆叠多层膜的生长提供了种子。 (C) 2003 年美国物理研究所。
Scanning tunneling microscopy with high impedance has been used to image the growth of pentacene thin films on Au(111). Instead of the herringbone structure in bulk solid, pentacene molecules in these thin films form a cofacial, pi-stacked crystalline phase with their molecular planes parallel to the surface. The growth of this crystalline phase is attributed to the formation of a close-packed, crystalline monolayer which seeds the growth of the pi-stacked multilayer film.
