In coupled nanostructures, however, the localization field depends strongly on coupling between confinement regions, complicating comparisons across geometries. Here, we show that ground-state electric-field-induced localization follows a common master curve governed by a single dimensionless parameter comparing electrostatic detuning and quantum coupling. Using a one-dimensional effective-mass model for the stacking direction of a disorder-free five-layer GaAs\/Al\n \n \n \n <\/jats:tex-math>\n \n \n \n \n \n 0.3<\/mml:mn>\n <\/mml:mrow>\n <\/mml:msub>\n <\/mml:mrow>\n <\/mml:math>\n <\/jats:inline-formula>\n Ga\n \n \n \n <\/jats:tex-math>\n \n \n \n \n \n 0.7<\/mml:mn>\n <\/mml:mrow>\n <\/mml:msub>\n <\/mml:mrow>\n <\/mml:math>\n <\/jats:inline-formula>\n As superlattice with\n \n \n \n <\/jats:tex-math>\n \n \n \n L<\/mml:mi>\n y<\/mml:mi>\n <\/mml:msub>\n =<\/mml:mo>\n 10<\/mml:mn>\n <\/mml:mrow>\n <\/mml:math>\n <\/jats:inline-formula>\n nm, we vary only the interlayer barrier thickness, changing the zero-field coupling scale by more than two orders of magnitude.

A five-site nearest-neighbor tight-binding model, with hopping fixed by the continuum zero-field manifold width, reproduces the master curve and predicts reduced thresholds within a few percent without additional fitted parameters. Small systematic departures occur in the strong-coupling regime at deep localization, where absolute fields produce intra-well deformation beyond a one-orbital description. These results establish, within this structural family, a simple connection between the zero-field electronic spectrum and the electric field required for nanoscale ground-state localization, providing a predictive framework for the design of field-tunable coupled quantum structures.\n <\/jats:p>","DOI":"10.1088\/1361-6528\/aeb810","type":"journal-article","created":{"date-parts":[[2026,10,22]],"date-time":"2026-10-22T22:48:33Z","timestamp":1792709313000},"page":"435001","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["One-parameter scaling of ground-state Stark localization in a five-layer semiconductor superlattice"],"prefix":"10.1088","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0522-0227","authenticated-orcid":true,"given":"Reyna","family":"M\u00e9ndez-Camacho","sequence":"first","affiliation":[{"name":"Universidad Aut\u00f3noma Metropolitana-Iztapalapa"},{"name":"Centro de Investigaci\u00f3n y de Estudios Avanzados del IPN"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"validation","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4647-6683","authenticated-orcid":true,"given":"M\u00e1ximo","family":"L\u00f3pez-L\u00f3pez","sequence":"additional","affiliation":[{"name":"Centro de Investigaci\u00f3n y de Estudios Avanzados del IPN"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"funding-acquisition","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"resources","vocabulary":"credit"},{"role":"validation","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7004-7638","authenticated-orcid":true,"given":"Esteban","family":"Cruz-Hern\u00e1ndez","sequence":"additional","affiliation":[{"name":"Universidad Aut\u00f3noma de San Luis Potos\u00ed"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"validation","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"}]}],"member":"266","published-online":{"date-parts":[[2026,10,30]]},"reference":[{"key":"nanoaeb810bib1","doi-asserted-by":"publisher","first-page":"2426","DOI":"10.1103\/PhysRevLett.60.2426","type":"journal-article","article-title":"Stark localization in GaAs-GaAlAs superlattices under an electric field","volume":"60","author":"Mendez","year":"1988","journal-title":"Phys.
