Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Cu6PS5I superionic thin films were deposited onto silicate glass substrates by non-reactive radio frequency magnetron sputtering. Optical transmission spectra of annealed and implanted by sulphur and phosphorous thin films were investigated. In the temperature interval 77–300 K the temperature behavior of optical absorption spectra and dispersion of refractive index of annealed films as well as the influence of ionic implantation on spectra and parameters of exponential absorption edge were studied. Temperature dependences of optical pseudogap, Urbach energy and refractive index of annealed and implanted Cu6PS5I thin films were analysed.
