Data confidence 85 high
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

In this study, we investigate the impact of electrochemical etching on the nanostructuring of Indium Phosphide (InP). The work explores the effects of electrolyte composition on the morphological and compositional properties of InP surface layers, particularly considering etching in a water solution of nitric acid and the same solution but with an addition of hydrochloric acid. The results show that InP samples etched with HCl exhibit evenly etched square pores and lower oxygen content, indicating a more controlled and anisotropic etching process.
