The structure–property link is inherent to materials. Hexagonal Ge4Se3Te phase, with special Ge–Ge cationic bonding and distinctive from other IV–VI compounds, reveals thermoelectric (TE) performance far below the common values for IV–VI compounds. Here, it is shown that its TE performance can be substantially enhanced by phase modulation: increasing sintering temperature from 573 to 773 K leads to...
