  • The high-temperature tetragonal phase of HfO2 is technologically useful but difficult to stabilize at room temperature. Here, the authors observe in real-time the transformation of a HfO2nanorod from its room temperature to tetragonal phase, at 1000° less than its bulk temperature, suggesting that size confinement may kinetically trap this phase.

  • Tuning the band gap of perovskite oxides is key for achieving tailored electronic properties in transistors, LEDs, photovoltaics, and scintillators. Here, by exploring all chemical combinations of 68 elements, machine learning is used to identify and predict stable synthesizable cubic perovskites with desired band gap values.
