“Pop‐art” like patterns resulting from the interaction of a single laser pulse focused on a‐Ge based chalcogenide thin film capped with a SiN layer are presented by Jérôme Gaudin and co‐workers. These nondeterministic surface patterns, described in article number 2003032, are wrinkles with a height of less than 100 nm and sub‐micrometer periodicity, which depends on the impinging laser fluence. Application as physical unclonable functions is demonstrated using a fast recognition algorithm.

硫属化物膜:激光在硫属化物玻璃膜中产生亚微米级皱纹,这是物理上不可克隆的功能(Adv。Mater。38/2020)

JérômeGaudin及其同事介绍了单个激光脉冲相互作用产生的“流行艺术”图案,这些激光脉冲聚焦在覆盖有SiN层的基于Ge的硫属化物薄膜上。编号为2003032的物品中描述的这些不确定的表面图案是高度小于100 nm的褶皱,其亚微米周期性取决于入射的激光通量。使用快速识别算法演示了作为物理不可克隆功能的应用。
