Retraction Note to: J Mater Sci: Mater Electron (2019) 30:4259–4269 https://doi.org/10.1007/s10854-019-00717-2
The Editor-in-Chief has retracted this article after concerns around images. Specifically:
All three images in Fig. 1 appear to be a very similar image at different scales, despite the legend saying that the samples were deposited at different temperatures.
There appears to be multiple similarities between curves a and b in Fig. 3, and in the 64+ range, all three curves appear very similar.
The authors did not respond to the request to submit raw images and data. The Editor-in-Chief, therefore, has lost confidence in the integrity of the article’s findings. The authors did not respond to correspondence from the Editor about this retraction.
