Self-assembled photonic cavities with atomic-scale confinement.

ABSTRACT: Despite tremendous progress in research on self-assembled nanotechnological building blocks, such as macromolecules¹, nanowires² and two-dimensional materials³, synthetic self-assembly methods that bridge the nanoscopic to macroscopic dimensions remain unscalable and inferior to biological self-assembly. By contrast, planar semiconductor technology has had an immense technological impact, owing to its inherent scalability, yet it seems unable to reach the atomic dimensions enabled by self-assembly. Here, we use surface forces, including Casimir-van der Waals interactions⁴, to deterministically self-assemble and self-align suspended silicon nanostructures with void features well below the length scales possible with conventional lithography and et
