Three-dimensional printed masks ensured good reproducibility during the PLD deposition of heterostructure samples. The samples were tested for electrical conductivity and AC photoconductivity by dielectric spectroscopy measurements. DC bias voltages and light were applied to the samples. The electrical capacity of the thin film heterostructure can be modified electrically and optically. We observed long-term photoconductivity with a time dependency that was not exponential, and a quick change of the electrical capacity, indicating the potential of the heterostructure cells as photodetector candidates.<\/jats:p>","DOI":"10.3390\/s22031143","type":"journal-article","created":{"date-parts":[[2022,2,6]],"date-time":"2022-02-06T20:40:18Z","timestamp":1644180018000},"page":"1143","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Capacitive Photodetector Thin-Film Cells of Cu-As2S3-Cu as Revealed by Dielectric Spectroscopy"],"prefix":"10.3390","volume":"22","author":[{"given":"Paul","family":"Ganea","sequence":"first","affiliation":[{"name":"National Institute of Materials Physics, 405A Atomistilor St., RO-077125 Magurele, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1992-7346","authenticated-orcid":false,"given":"Gabriel","family":"Socol","sequence":"additional","affiliation":[{"name":"National Institute for Laser, Plasma and Radiation Physics, 409Atomistilor St., RO-077125 Magurele, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sorin","family":"Zamfira","sequence":"additional","affiliation":[{"name":"Department of Product Design, Mechatronics and Environment, Transilvania University of Bra\u015fov, 29 Eroilor Blvd., RO-500036 Bra\u0219ov, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1741-8617","authenticated-orcid":false,"given":"Nicolae","family":"Cre\u0163u","sequence":"additional","affiliation":[{"name":"Department of Product Design, Mechatronics and Environment, Transilvania University of Bra\u015fov, 29 Eroilor Blvd., RO-500036 Bra\u0219ov, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8387-2562","authenticated-orcid":false,"given":"Elena","family":"Matei","sequence":"additional","affiliation":[{"name":"National Institute of Materials Physics, 405A Atomistilor St., RO-077125 Magurele, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adam","family":"L\u0151rinczi","sequence":"additional","affiliation":[{"name":"National Institute of Materials Physics, 405A Atomistilor St., RO-077125 Magurele, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,2,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.jnoncrysol.2003.08.064","article-title":"Optical properties and applications of chalcogenide glasses: A review","volume":"330","author":"Zakery","year":"2003","journal-title":"J.
