Joule influence of strain on phase stability
Nettet18. aug. 2016 · Applying a compressive biaxial in-plane strain and perpendicular tensile strain in ranges where the structure is still stable leads to a topological phase transition. We also examine the influence of strain on zigzag phosphorene nanoribbons (zPNRs) and the formation of the corresponding protected edge states when the system is in the … NettetWe demonstrate that this ferroelectric phase can be preferentially stabilized in non-ferroelectric MXenes through full chemical substitution of Sc or O, alloying of the Sc sites, or application of epitaxial strain. Finally, we show that these materials have excellent piezoelectric properties as well.

This enables not only an extremely low κL close to its amorphous limit but also an establishment of fundamentals on strain engineering for κL minimization.
Nettet11. des. 2024 · [15,16] studied the influence of strain on the structure, electric polarization and magnetization of BiFeO 3. The electric polarization is found to be rather independent of strain, in striking contrast to most conventional perovskite ferroelectrics. NettetImportantly, the devices after strain modulation exhibited a remarkable long-term operational stability by maintaining 83.60% of initial PCE after 2500 h maximum power point (MPP) tracking. Finally, we combined the optimized perovskite top cells with silicon bottom cells to fabricate two-terminal tandem solar cells, yielding a PCE of 26.95%.
