work explores the deposition of hexagonal (h-) LuMnO3 thin films in the P63cm phase and investigates the conditions under which the synergy of ferroelectric and photoactive properties, can be achieved to confirm the potential of this material for applications in the development of next-generation photovoltaic devices. Single-phase h-LuMnO3 was successfully deposited on different substrates, and the thermal stability of the material was confirmed by Micro-Raman spectroscopy analysis from 77 to 850 K, revealing the suitable ferro- to para-electric transition near 760 K. Optical measurements confirm the relatively narrow band gap at 1.5 eV, which corresponds to the h-LuMnO3 system. The presence of domain structures and the signature of hysteresis loops consistent with ferroelectric behaviour were confirmed by piezoresponse force microscopy. In addition, light-dependent photocurrent measurements revealed the photoactive sensitivity of the material.<\/jats:p>","DOI":"10.3390\/ma18051058","type":"journal-article","created":{"date-parts":[[2025,2,27]],"date-time":"2025-02-27T05:13:58Z","timestamp":1740633238000},"page":"1058","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Low-Bandgap Ferroelectric h-LuMnO3 Thin Films for Photovoltaic Applications"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2845-7216","authenticated-orcid":false,"given":"Abderrazzak","family":"Ait Bassou","sequence":"first","affiliation":[{"name":"Centro de Qu\u00edmica-Vila Real, CQ-VR, Physics Department, Escola de Ci\u00eancias e Tecnologia (ECT), University of Tr\u00e1s-os-Montes e Alto Douro, 5001-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2986-7818","authenticated-orcid":false,"given":"Lisete","family":"Fernandes","sequence":"additional","affiliation":[{"name":"Centro de Qu\u00edmica-Vila Real, CQ-VR, Unidade de Microscopia Eletr\u00f3nica-Centro de Investiga\u00e7\u00e3o e Desenvolvimento UME\/CIDE, University of Tr\u00e1s-os-Montes e Alto Douro, 5000-801 Vila Real, Portugal"}]},{"given":"Denis O.","family":"Alikin","sequence":"additional","affiliation":[{"name":"CICECO Aveiro Institute of Materials, Physics Department, Campus de Santiago, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"given":"Mafalda S.","family":"Moreira","sequence":"additional","affiliation":[{"name":"Instituto de F\u00edsica de Materiais Avan\u00e7ados, Nanotecnologia e Fot\u00f3nica (IFIMUP), Departamento de F\u00edsica e Astronomia, Faculdade Ci\u00eancias da Universidade Porto, R.
