Here, we explore how tensile strain and external electric fields can modulate its electronic bands and topological characteristics using first-principles density functional theory combined with model Hamiltonian approaches. All calculations are performed within the plane-wave pseudopotential framework, including spin\u2013orbit coupling, and maximally localized Wannier functions are employed to analyze the Berry curvature, Fermi arcs, and node evolution. Under a 4% tensile strain, NbP develops a small band gap of \u223c0.05 eV along the \u0393\u2013\u03a3 direction, accompanied by a reduction in carrier density near the Fermi energy. Increasing strain to 8% leads to a gap of \u223c0.035 eV and further suppression of Fermi-level states, indicating strain-driven band reorganization. The application of electric fields produces minute but significant effects: at 0.51 V \u00c5\n                    <jats:sup>\u22121<\/jats:sup>\n                    , band curvature shifts slightly, while at 1.29 V \u00c5\n                    <jats:sup>\u22121<\/jats:sup>\n                    , a gap of \u223c0.02 eV opens along the \u0393\u2013\n                    <jats:italic>S<\/jats:italic>\n                    path. This controlled gap opening signifies a transition toward switchable electronic phases, highlighting NbP\u2019s potential in topological electronics and field-tunable quantum devices.\n                  <\/jats:p>","DOI":"10.1088\/1361-648x\/ae50a2","type":"journal-article","created":{"date-parts":[[2026,3,20]],"date-time":"2026-03-20T07:29:18Z","timestamp":1773991758000},"page":"115501","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Field-driven electronic and topological modulation in the Weyl semimetal NbP"],"prefix":"10.1088","volume":"38","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-9367-7159","authenticated-orcid":true,"given":"Ga\u00ebl-Pac\u00f4me","family":"Nguimeya Tematio","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2228-058X","authenticated-orcid":true,"given":"Trisha","family":"Salagaram","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6712-7821","authenticated-orcid":true,"given":"Aniekan Magnus","family":"Ukpong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3371-5574","authenticated-orcid":true,"given":"Houssam Eddine","family":"Hailouf","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kingsley Onyebuchi","family":"Obodo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"266","published-online":{"date-parts":[[2026,3,20]]},"reference":[{"key":"cmae50a2bib1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevB.92.115428","type":"journal-article","article-title":"Topological surface states and Fermi arcs of the noncentrosymmetric Weyl semimetals TaAs, TaP, NbAs, and NbP","volume":"92","author":"Sun","year":"2015","journal-title":"Phys.
