Boosting room-temperature thermoelectricity in SrTiO<sub>3</sub>-based superlattices
Introducing tensile strain into STO-based superlattices increases the ferroelectric transition temperature, leading to phonon softening at elevated temperatures, which in turn boosts their dimensionless figure of merit ( ZT ) to 1.2.
