We report bottom-up synthesis of atomically-precise one-dimensional (1D) arrays of point charges on graphene that allow exploration of a new type of supercritical confinement of graphene carriers. The arrays were synthesized by arranging F<jats:sub>4<\/jats:sub>TCNQ molecules into a 1D lattice on back-gated graphene, allowing precise tuning of both the molecular charge and the array periodicity. While dilute arrays of ionized F<jats:sub>4<\/jats:sub>TCNQ molecules are seen to behave like isolated subcritical charges, dense arrays show emergent supercriticality. In contrast to compact supercritical clusters, these extended arrays display both supercritical and subcritical characteristics and belong to a new physical regime termed \u201cfrustrated supercritical collapse\u201d. Here carriers in the far-field are attracted by a supercritical charge distribution, but their fall to the center is frustrated by subcritical potentials in the near-field, similar to trapping of light by a dense cluster of stars in general relativity.<\/jats:p>","DOI":"10.1038\/s41467-019-08371-2","type":"journal-article","created":{"date-parts":[[2019,1,29]],"date-time":"2019-01-29T11:03:17Z","timestamp":1548759797000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Frustrated supercritical collapse in tunable charge arrays on graphene"],"prefix":"10.1038","volume":"10","author":[{"given":"Jiong","family":"Lu","sequence":"first","affiliation":[]},{"given":"Hsin-Zon","family":"Tsai","sequence":"additional","affiliation":[]},{"given":"Alpin N.","family":"Tatan","sequence":"additional","affiliation":[]},{"given":"Sebastian","family":"Wickenburg","sequence":"additional","affiliation":[]},{"given":"Arash A.","family":"Omrani","sequence":"additional","affiliation":[]},{"given":"Dillon","family":"Wong","sequence":"additional","affiliation":[]},{"given":"Alexander","family":"Riss","sequence":"additional","affiliation":[]},{"given":"Erik","family":"Piatti","sequence":"additional","affiliation":[]},{"given":"Kenji","family":"Watanabe","sequence":"additional","affiliation":[]},{"given":"Takashi","family":"Taniguchi","sequence":"additional","affiliation":[]},{"given":"Alex","family":"Zettl","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3462-524X","authenticated-orcid":false,"given":"Vitor M.","family":"Pereira","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8246-3444","authenticated-orcid":false,"given":"Michael F.","family":"Crommie","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2019,1,29]]},"reference":[{"key":"8371_CR1","doi-asserted-by":"publisher","first-page":"1522","DOI":"10.1126\/science.aaf5481","volume":"353","author":"S Chen","year":"2016","unstructured":"Chen, S. et al.
