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

Changes in the atomic structure and optical properties of amorphous films in the As-Se system upon annealing have been studied on films prepared by thermal evaporation in a vacuum and by RF ion-plasma sputtering. The annealing modifies the atomic structure of the films and shifts their optical absorption edge. Changes in the atomic structure mainly occur in the medium-range order. The most essential changes in the atomic structure and optical properties are observed for AsSe films. A correlation between changes in the medium-range order of the atomic structure and the optical gap of the films is established.
