The invention comprises at least the steps of (i) producing a deposition template from said master stamp, (ii) synthesis of a plasmonic particle colloid, (iii) producing an optically active, two-dimensional security tag template using self-assembly of said particles on said deposition template, (iv) producing a customized secure identity device from said security tag template by selective removal or modification of optical properties using ultrashort laser pulses. The produced customized plasmonic-photonic device can then be used as secure identity and anti-counterfeiting means. The device exploits customized spatial control and modification of optically active plasmonic particle arrays demonstrating surface lattice resonance optical signature to produce easily identifiable security features.

专利号:US-9923142-B2 优先权日:2016-05-31 标 题:Methods of graphene growth and related structures 发明人:CHEN MIIN-JANG; PAN SAMUEL C; HSIEH CHUNG-YEN 权利人:TAIWAN SEMICONDUCTOR MFG CO LTD; UNIV NAT TAIWAN 摘要:A method and structure for providing uniform, large-area graphene by way of a transfer-free, direct-growth process. In some embodiments, a SAM is used as a carbon source for direct graphene synthesis on a substrate. For example, a SAM is formed on an insulating surface, and a metal layer is formed over the SAM. The metal layer may serve as a catalytic metal, whereby the SAM is converted to graphene following an annealing process. The SAM is deposited using a VPD process (e.g., an ALD process and/or an MLD process). In some embodiments, a CNT having a controlled diameter may be formed on the surface of a nanorod by appropriately tuning the geometry of the nanorod. Additionally, in some embodiments, a curved graphene transistor may be formed over a curved oxide surface, thereby providing a band gap in a channel region of the graphene transistor.
