This is particularly true for ultrathin films made of discrete molecular layers. In this work, Spectroscopy Ellipsometry and Scanning Capacitance Microscopy were used to study thin films made of <jats:italic>N<\/jats:italic>,<jats:italic>N<\/jats:italic>\u2032\u2010bis(<jats:italic>n<\/jats:italic>\u2010octyl)\u2010<jats:italic>x<\/jats:italic>:<jats:italic>y<\/jats:italic>,dicyanoperylene\u20103,4\u2009:\u20099,10\u2010bis(dicarboximide). The relative dielectric constant presents a non\u2010monotonic trend with thickness: it is equal to 2.1 for one molecular layer, saturating at 3.2 for increasing thickness. This maximum value, equivalent to the bulk one, occurs when the coverage is in between the third to the fourth layer. In this range, the growth switches from a Frank\u2013Van der Merwe (2D growth) to a Volmer\u2010Weber mode (3D growth); in addition, the molecular configuration assumes a bent\/distorted geometry with respect to the initial edge\u2010on one. These results establish a morphological dependence of the dielectric constant, especially in the vicinity of the substrate interface, that disappears at a certain distance from it.<\/jats:p>","DOI":"10.1002\/cphc.202400580","type":"journal-article","created":{"date-parts":[[2024,7,17]],"date-time":"2024-07-17T06:38:48Z","timestamp":1721198328000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Thickness\u2010Dependent Relative Dielectric Constant of Organic Ultrathin Films"],"prefix":"10.1002","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4433-5377","authenticated-orcid":false,"given":"Caterina","family":"Summonte","sequence":"first","affiliation":[{"name":"Consiglio Nazionale delle Ricerche - Istituto per la Microelettronica e Microsistemi (CNR-IMM)  Via Gobetti 101 40129 Bologna Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4659-4329","authenticated-orcid":false,"given":"Francesco","family":"Borgatti","sequence":"additional","affiliation":[{"name":"Consiglio Nazionale delle Ricerche - Istituto per lo Studio dei Materiali Nanostrutturati (CNR-ISMN)  Via Gobetti 101 40129 Bologna Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5665-0788","authenticated-orcid":false,"given":"Cristiano","family":"Albonetti","sequence":"additional","affiliation":[{"name":"Consiglio Nazionale delle Ricerche - Istituto per lo Studio dei Materiali Nanostrutturati (CNR-ISMN)  Via Gobetti 101 40129 Bologna Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,9,11]]},"reference":[{"key":"e_1_2_8_1_1","doi-asserted-by":"publisher","DOI":"10.1002\/pol.20210457"},{"key":"e_1_2_8_2_1","doi-asserted-by":"crossref","unstructured":"G.
