Abstract

We demonstrate that atomically smooth surfaces can be generated by thermoplastic forming of metallic glasses. This is enabled by the flow associated with the contact-line motion which removes rough surface layer from the advancing metallic glass-air interface. The thermoplastically formed surface is two orders of magnitude smoother than a polished surface of the same alloy. This process is capable of generating atomically smooth surfaces and replicating nanoscale features in a single processing step, providing a versatile toolbox for nanofabrication.
