Machine learning-assisted ultrafast flash sintering of high-performance and flexible silver–selenide thermoelectric devices

The first machine learning-assisted ultrafast flash sintering of flexible silver–selenide TE devices. Bayesian optimization of flash sintering variables led to a PF of 2205 μW m −1 K −2 and a zT of 1.1 at room temperature realized with a sintering time less than 1.0 second.
