Chip Security To protect semiconductor chips, an information-encoded label is designed, fabricated, and transferred onto an electronic chip. In this label, colloidal quantum wells with ultra-low emission bandwidth were utilized. Each color bar represents a specific information. The nanoparticles are randomly distributed on the boundaries of the color bars, making the information secure and unclonable. More details can be found in the Research Article by Hilmi Volkan Demir and co-workers (DOI: 10.1002/adom.202502884).
