光记录有机薄膜的扫描隧道显微镜研究

Scanning Tunneling Microscopy Studies of Organic Films in Optical Recording

运用扫描隧道显微镜（ＳＴＭ）观察了光记录有机薄膜的微观结构。从微观结构的形貌可以看出光记录后酞菁薄膜上产生了鼓泡。不同能量的激光脉冲产生具有不同细微结构的鼓泡，光盘的性能与鼓泡的尺寸密切相关。研究结果说明ＳＴＭ是研究光盘微观结构的有力工具。

In this paper, scanning tunneling microscopy (STM) is used to investigate the microstructure of organic films in optical recording. Bubbles are found for phthalocyanine thin films after laser irradiation. Laser pulses of different energies produce bubbles of various minute structures. The disc performance closely correlates with the sizes of the bubbles. It is demonstrated that STM is a powerful tool to investigate the microstructure of the optical disc.
