Autonomous robotic nanofabrication with reinforcement learning [PDF]
Sci. Adv. 6, eabb6987 (2020), 2020 The ability to handle single molecules as effectively as macroscopic building-blocks would enable the construction of complex supramolecular structures inaccessible to self-assembly. The fundamental challenges obstructing this goal are the uncontrolled variability and poor observability of atomic-scale conformations. Here, we present a strategy to work

Plasmonics as a fabrication tool [PDF]
arXiv, 2020 Plasmonic nanolithography is a nanofabrication technique which exploits surface plasmons to generate subdiffraction patterns. In this review, we highlight the key concepts in plasmonic nanolithography, review the pioneering papers and provide a classification that can be useful in determining the proper method and tool for subdiffraction patterning ...
