We explore the possibility that the C2\/m, C2\/c, the disordered Im-3m, and the I4\/mmm phases observed in sesquichalcogenides with heavier cations, viz. Bi2Se3, Bi2Te3, and Sb2Te3, could also be formed in Sb2S3, Sb2Se3, and Bi2S3, as suggested from recent experiments. Our calculations show that the C2\/c phase is not energetically favorable in any of the three compounds, up to 60 GPa. The C2\/m system is also unfavorable for Sb2S3 and Bi2S3; however, it is energetically favorable with respect to the Pnma phase of Sb2Se3 above 10 GPa. Finally, the I4\/mmm and the disordered body-centered cubic-type Im-3m structures are competitive in energy and are energetically more stable than the C2\/m phase at pressures beyond 30 GPa. The dynamical stabilities of the Pnma, Im-3m, C2\/m, and I4\/mmm structural phases at high pressures are discussed for the three compounds.<\/jats:p>","DOI":"10.3390\/cryst13030498","type":"journal-article","created":{"date-parts":[[2023,3,15]],"date-time":"2023-03-15T05:22:59Z","timestamp":1678857779000},"page":"498","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Theoretical Study of Pressure-Induced Phase Transitions in Sb2S3, Bi2S3, and Sb2Se3"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7093-3266","authenticated-orcid":false,"given":"Estelina Lora","family":"da Silva","sequence":"first","affiliation":[{"name":"IFIMUP, Institute of Physics for Advanced Materials, Nanotechnology and Photonics, Department of Physics and Astronomy, Faculty of Sciences, University of Porto, Rua do Campo Alegre, 687, 4169-007 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3114-7473","authenticated-orcid":false,"given":"Mario C.","family":"Santos","sequence":"additional","affiliation":[{"name":"Instituto dos Pupilos do Ex\u00e9rcito, Estrada de Benfica, n\u00ba 374, 1549-016 Lisboa, Portugal"},{"name":"Instituto de Dise\u00f1o para la Fabricaci\u00f3n y Producci\u00f3n Automatizada, MALTA Consolider Team, Universitat Polit\u00e8cnica de Val\u00e8ncia, 46022 Val\u00e8ncia, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4148-6516","authenticated-orcid":false,"given":"Pl\u00e1cida","family":"Rodr\u00edguez-Hern\u00e1ndez","sequence":"additional","affiliation":[{"name":"Departamento de F\u00edsica, Instituto de Materiales y Nanotecnolog\u00eda, MALTA Consolider Team, Universidad de La Laguna, 38200 Tenerife, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3347-6518","authenticated-orcid":false,"given":"Alfonso","family":"Mu\u00f1oz","sequence":"additional","affiliation":[{"name":"Departamento de F\u00edsica, Instituto de Materiales y Nanotecnolog\u00eda, MALTA Consolider Team, Universidad de La Laguna, 38200 Tenerife, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3926-1705","authenticated-orcid":false,"given":"Francisco Javier","family":"Manj\u00f3n","sequence":"additional","affiliation":[{"name":"Instituto de Dise\u00f1o para la Fabricaci\u00f3n y Producci\u00f3n Automatizada, MALTA Consolider Team, Universitat Polit\u00e8cnica de Val\u00e8ncia, 46022 Val\u00e8ncia, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"178","DOI":"10.1126\/science.1173034","article-title":"Experimental Realization of a Three-Dimensional Topological Insulator, Bi2Te3","volume":"325","author":"Chen","year":"2009","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"438","DOI":"10.1038\/nphys1270","article-title":"Topological insulators in Bi2Se3, Bi2Te3 and Sb2Te3 with a single Dirac cone on the surface","volume":"5","author":"Zhang","year":"2009","journal-title":"Nat.
