It is our great pleasure to introduce this second edition of the focus issue on phase-change and ovonic materials. This special aims summarize recent progress in rapidly developing field materials their numerous applications. provides a snapshot state-of-the-art, both experimental theoretical, for experienced young researchers interested subject area. Since its very first 2019, we expect publis...

Once again, it is our great pleasure to continue the E\PCOS tradition by presenting this fourth edition of special issue on Phase-Change and Ovonic Materials that published each year as part European Symposium Sciences (E\PCOS). We have admit 2022 had a spirit marked long-awaited return face-to-face on-site symposium after two-year hiatus due Covid crisis. Last September, was most successful in...

Colloidal nanocrystals have long been used to study the dependence of phase stability and transitions on size. Both structural phase stability and phase transitions change dramatically in the nanometre size regime where the surface plays a significant role in determining the overall energetics of the system. We investigate the solid–solid phase transformation of crystallization in amorphous GeT...
