One of the candidate materials with promising properties is cadmium zinc telluride (CdZnTe). In the context of this article, we have developed pixelated sensors from CdZnTe crystals grown by Boron oxide encapsulated vertical Bridgman technique. We demonstrate the successful fabrication of CdZnTe pixel sensors with a fine pitch of 55 m and thickness of 1 mm and 2 mm. The sensors were bonded on Timepix readout chips to evaluate their response to X-rays provided by conventional sources. Despite the issues related to single-chip fabrication procedure, reasonable uniformity was achieved along with low leakage current values at room temperature. In addition, the sensors show stable performance over time at moderate incoming fluxes, below 106 photons mm\u22122s\u22121.<\/jats:p>","DOI":"10.3390\/s21092932","type":"journal-article","created":{"date-parts":[[2021,4,22]],"date-time":"2021-04-22T21:25:56Z","timestamp":1619126756000},"page":"2932","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Fabrication of Small-Pixel CdZnTe Sensors and Characterization with X-rays"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6393-2302","authenticated-orcid":false,"given":"Stergios","family":"Tsigaridas","sequence":"first","affiliation":[{"name":"European Synchrotron Radiation Facility (ESRF), 71 Avenue des Martyrs, F-38043 Grenoble, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4330-0831","authenticated-orcid":false,"given":"Silvia","family":"Zanettini","sequence":"additional","affiliation":[{"name":"Due2lab s.r.l., via Paolo Borsellino 2, 42019 Scandiano, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4062-3782","authenticated-orcid":false,"given":"Manuele","family":"Bettelli","sequence":"additional","affiliation":[{"name":"IMEM-CNR, Istituto Materiali per l\u2019Elettronica e il Magnetismo, Consiglio Nazionale delle Ricerche, Parco Area delle Scienze 37\/A, 43124 Parma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6932-7827","authenticated-orcid":false,"given":"Nicola Sarzi","family":"Amad\u00e8","sequence":"additional","affiliation":[{"name":"IMEM-CNR, Istituto Materiali per l\u2019Elettronica e il Magnetismo, Consiglio Nazionale delle Ricerche, Parco Area delle Scienze 37\/A, 43124 Parma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3344-8007","authenticated-orcid":false,"given":"Davide","family":"Calestani","sequence":"additional","affiliation":[{"name":"IMEM-CNR, Istituto Materiali per l\u2019Elettronica e il Magnetismo, Consiglio Nazionale delle Ricerche, Parco Area delle Scienze 37\/A, 43124 Parma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cyril","family":"Ponchut","sequence":"additional","affiliation":[{"name":"European Synchrotron Radiation Facility (ESRF), 71 Avenue des Martyrs, F-38043 Grenoble, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Zappettini","sequence":"additional","affiliation":[{"name":"IMEM-CNR, Istituto Materiali per l\u2019Elettronica e il Magnetismo, Consiglio Nazionale delle Ricerche, Parco Area delle Scienze 37\/A, 43124 Parma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"P01007","DOI":"10.1088\/1748-0221\/11\/01\/P01007","article-title":"Review of hybrid pixel detector readout ASICs for spectroscopic X-ray imaging","volume":"11","author":"Ballabriga","year":"2016","journal-title":"J.
