A chemical link between Ge–Sb–Te and In–Sb–Te phase-change materials†
Abstract
We identify a similar feature in the chemical-bonding nature of seemingly different phase-change materials (PCMs) for data storage. This affords new insight into the “next-generation” material In3SbTe2, establishes a hitherto missing link to the more ubiquitous Ge–Sb–Te alloys, and encourages the search for new PCMs beyond established electron-counting schemes.
