Periodic domain inversion in single crystal barium titanate-on-insulator thin film
Pragati Aashna, Hong-Lin Lin, Yu Cao +5
We report experimentally achieving first-ever electric field periodic poling of single crystal barium titanate (BTO, or BaTiO3) thin film on insulator. Owing to the outstanding opt…
