      abstract     = {Elemental phosphorus nanostructures are notorious for a
                      large number of allotropes, which limits their usefulness as
                      semiconductors. To limit this structural diversity, we
                      synthesize selectively quasi-1D phosphorus nanostructures
                      inside carbon nanotubes (CNTs) that act both as stable
                      templates and nanoreactors. Whereas zigzag phosphorus
                      nanoribbons form preferably in CNTs with an inner diameter
                      exceeding 1.4 nm, a previously unknown square columnar
                      structure of phosphorus is observed to form inside narrower
                      nanotubes. Our findings are supported by electron microscopy
                      and Raman spectroscopy observations as well as ab initio
                      density functional theory calculations. Our computational
                      results suggest that square columnar structures form
                      preferably in CNTs with an inner diameter around 1.0 nm,
                      whereas black phosphorus nanoribbons form preferably inside
                      CNTs with a 4.1 nm inner diameter, with zigzag nanoribbons
                      energetically favored over armchair nanoribbons. Our
                      theoretical predictions agree with the experimental
                      findings},
