Owing to the central hollow B atoms strongly hybridized to the hydro-\/halogen adatoms, adequate charge transfer is induced from the hollow B to the basal honeycomb B sublattice, which electronically stabilizes the 2D sheet and decisively endows a robust (intrinsic and stable-against-strains) graphene-like Dirac cone state. The predicted high energetic, dynamic and thermal stabilities, combined with pretty geometrical match to the commonly utilized Ag\/Au(111) substrates, support their experimental viabilities. Our prediction provides a new branch for exploring the intriguing 2D Dirac fermionic states in versatile boron element and its derivatives.<\/jats:p>","DOI":"10.1088\/1361-648x\/ad7e73","type":"journal-article","created":{"date-parts":[[2024,9,23]],"date-time":"2024-09-23T22:57:33Z","timestamp":1727132253000},"page":"505304","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Robust massless Dirac fermions in hydro-\/halogenated trigonal borophene"],"prefix":"10.1088","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9835-9729","authenticated-orcid":true,"given":"L-B","family":"Meng","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D X","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S","family":"Ni","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8952-2822","authenticated-orcid":true,"given":"Z M","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"W M","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"266","published-online":{"date-parts":[[2024,10,1]]},"reference":[{"key":"cmad7e73bib1","doi-asserted-by":"publisher","first-page":"666","DOI":"10.1126\/science.1102896","article-title":"Electric field effect in atomically thin carbon films","volume":"306","author":"Novoselov","year":"2004","journal-title":"Science"},{"key":"cmad7e73bib2","doi-asserted-by":"publisher","first-page":"611","DOI":"10.1038\/nphoton.2010.186","article-title":"Graphene photonics and optoelectronics","volume":"4","author":"Bonaccorso","year":"2010","journal-title":"Nat.
