First-principles calculations under pressure reveal a moderate increase in the density of states (DOS) up to ~\u200910 GPa, followed by a slight decrease for higher pressures, a trend which is similar to the observed critical temperature. Furthermore, from theory it is clear that the structure remains stable up to approximately 30 GPa.\n                  <\/jats:p>","DOI":"10.1038\/s41598-026-40887-8","type":"journal-article","created":{"date-parts":[[2026,3,10]],"date-time":"2026-03-10T12:19:32Z","timestamp":1773145172000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Impact of pressure on the structural, Raman, superconducting, and normal state resistivity properties of Y5Rh6Sn18 quasi-skutterudite single crystal"],"prefix":"10.1038","volume":"16","author":[{"given":"Govindaraj","family":"Lingannan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muthukumaran","family":"Sundaramoorthy","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thiagarajan","family":"Maran","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anwesha","family":"Chakraborty","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chia Nung","family":"Kuo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chin Shan","family":"Lue","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Debjani","family":"Karmakar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Delin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olle","family":"Eriksson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mahmoud","family":"Abdel-Hafiez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sonachalam","family":"Arumugam","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Boby","family":"Joseph","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,3,10]]},"reference":[{"key":"40887_CR1","doi-asserted-by":"publisher","first-page":"839","DOI":"10.1016\/0038-1098(80)90125-8","volume":"36","author":"JL Hodeau","year":"1980","unstructured":"Hodeau, J.
