Abstract A scalable method is presented for direct patterning of graphite and transition metal dichalcogenide (TMD) films on polycarbonate (PC) other transparent substrates using fiber laser ablation. This process facilitates the fabrication various functional devices, including strain gauges, supercapacitors, photodetector arrays, without need photolithography or solvents, thereby simplifying device production enhancing environmental sustainability. Utilizing roll‐to‐roll mechanical exfoliation, homogeneous nanosheet are created then patterned with a engraving system. Electrical optical characterization confirms that laser‐processed maintain their crystallinity, no observable damage to underlying substrate. The scalability this approach demonstrated by constructing WSe 2 /graphite array PC, which exhibits high sensitivity, low noise, uniform photocurrent response across its active channels.

Abstract Integrated circuit anti-counterfeiting based on optical physical unclonable functions (PUFs) plays a crucial role in guaranteeing secure identification and authentication for Internet of Things (IoT) devices. While considerable efforts have been devoted to exploring PUFs, two critical challenges remain: incompatibility with the complementary metal-oxide-semiconductor (CMOS) technology limited information entropy. Here, we demonstrate all-silicon multidimensionally-encoded PUFs fabricated by integrating silicon (Si) metasurface erbium-doped Si quantum dots (Er-Si QDs) CMOS-compatible procedure. Five in-situ responses manifested within single pixel, rendering an ultrahigh entropy 2.32 bits/pixel. The position-dependent originate from radiation field Purcell effect. Our evaluation highlights their potential IoT security through advanced metrics like bit uniformity, similarity, intra- inter-Hamming distance, false-acceptance rejection rates, encoding capacity. We finally implementation efficient lightweight mutual protocols applications using all-Si PUFs.
