摘要：
Surface engineering over multiple length scales is critical for electronics, photonics, and enabling multifunctionality in synthetic materials. Here, we demonstrate a sequential embossing technique for building multi-tier patterns in metals by controlling the size-dependent thermoplastic forming of metallic glasses. Sub-100 nm to millimeter sized features are sculpted sequentially to allow an exquisite control of surface properties. The process can be integrated with net-shaping to transfer functional patterns on three-dimensional metal parts.
