recommendations! Published in 2025 at "Advanced Functional Materials"

DOI: 10.1002/adfm.202423198

Abstract: Quantitatively probing sub‐nanometer elementary structural units of amorphous materials, such as amorphous silicon (a‐Si), is essential for Si‐based technological progress. However, accurately identifying and quantifying short‐range order (SRO) and dangling bond/floating bond (DB/FB) defects over… read more here.
