Summary
[edit]| Description |
English: Supplementary Movie 6 Mechanism of pressure-induced phase transition from stripe-type-λ-Ti3O5 to β-Ti3O5. This movie shows the mechanism of pressure-induced phase transition using the thermodynamic model proposed by Slichter and Drickamer. Gibbs free energy (G) versus λ-Ti3O5 fraction (x) curves show that λ-Ti3O5 phase (blue) is maintained at all temperatures due to the energy barrier originated from cooperative interaction between the two phases. Then, the 300 K curve is focused, showing its pressure dependence. At 60 MPa, the energy barrier disappears, and λ-Ti3O5 phase converts into β-Ti3O5 phase (red). Finally, heat storage process from β-Ti3O5 to λ-Ti3O5 is shown with G versus x and x versus temperature curves. Such a metal oxide is the first example. |
