The strain engineering and strain control of the ferroelectric properties of layered two-dimensional van der Waals materials, such as CuInP2(S,Se)6 monolayers, thin films, and nanoflakes, are of fundamental interest and especially promising for their advanced applications in nanoscale nonvolatile memories, energy conversion and storage, nano-coolers, and sensors. Here, we study the polar, piezoelectric, electrocaloric, and pyroelectric properties of thin strained films of a ferrielectric CuInP2S6 covered by semiconducting electrodes and reveal an unusually strong effect of a mismatch strain on these properties. In particular, the sign\u00a0of the mismatch strain and its magnitude determine the complicated behavior of piezoelectric, electrocaloric, and pyroelectric responses. The strain effect on these properties is opposite, i.e., \u201canomalous,\u201d in comparison with many other ferroelectric films, for which the out-of-plane remanent polarization, piezoelectric, electrocaloric, and pyroelectric responses increase strongly for tensile strains and decrease or vanish for compressive strains.<\/jats:p>","DOI":"10.1063\/5.0178854","type":"journal-article","created":{"date-parts":[[2023,12,6]],"date-time":"2023-12-06T15:59:51Z","timestamp":1701878391000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":7,"title":["The strain-induced transitions of the piezoelectric, pyroelectric, and electrocaloric properties of the CuInP2S6 films"],"prefix":"10.1063","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8505-458X","authenticated-orcid":false,"given":"Anna N.","family":"Morozovska","sequence":"first","affiliation":[{"name":"Institute of Physics, National Academy of Sciences of Ukraine 1 , 46, Prospekt Nauky, 03028 Kyiv, Ukraine"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8124-8857","authenticated-orcid":false,"given":"Eugene A.","family":"Eliseev","sequence":"additional","affiliation":[{"name":"Frantsevich Institute for Problems of Materials Science, National Academy of Sciences of Ukraine 2 , 3, Omeliana Pritsaka, 03142 Kyiv, Ukraine"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0345-9971","authenticated-orcid":false,"given":"Lesya P.","family":"Yurchenko","sequence":"additional","affiliation":[{"name":"Frantsevich Institute for Problems of Materials Science, National Academy of Sciences of Ukraine 2 , 3, Omeliana Pritsaka, 03142 Kyiv, Ukraine"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3072-247X","authenticated-orcid":false,"given":"Valentyn V.","family":"Laguta","sequence":"additional","affiliation":[{"name":"Frantsevich Institute for Problems of Materials Science, National Academy of Sciences of Ukraine 2 , 3, Omeliana Pritsaka, 03142 Kyiv, Ukraine"},{"name":"Institute of Physics, Czech Academy of Sciences 3 , 18200 Prague, Czech Republic"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0152-1783","authenticated-orcid":false,"given":"Yongtao","family":"Liu","sequence":"additional","affiliation":[{"name":"Center for Nanophase Materials Sciences, Oak Ridge National Laboratory 4 , Oak Ridge, Tennessee 37922, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5354-6152","authenticated-orcid":false,"given":"Sergei V.","family":"Kalinin","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, University of Tennessee 5 , Knoxville, Tennessee 37996, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3432-7610","authenticated-orcid":false,"given":"Andrei L.","family":"Kholkin","sequence":"additional","affiliation":[{"name":"Department of Physics and CICECO\u2014Aveiro Institute of Materials, Campus Universitario de Santiago 6 , 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2501-1780","authenticated-orcid":false,"given":"Yulian M.","family":"Vysochanskii","sequence":"additional","affiliation":[{"name":"Institute of Solid-State Physics and Chemistry, Uzhhorod University 7 , 88000 Uzhhorod, Ukraine"}]}],"member":"317","published-online":{"date-parts":[[2023,12,6]]},"reference":[{"key":"2023120615593957300_c1","doi-asserted-by":"publisher","first-page":"031102","DOI":"10.1063\/1.4958327","article-title":"Direct and indirect measurements on electrocaloric effect: Recent developments and perspectives","volume":"3","year":"2016","journal-title":"Appl.
