We found that the cooling process of low CTE metals during rapid thermal annealing (RTA) generates in-plane tensile stresses in the film, This facilitates an increase in the volume fraction of the o-phase and significantly improves the domain switching speed. However, no significant benefit was observed at electric fields less than 1 MV/cm. This is because at low voltage operation, the defective resistance (dead layer) within the interface pr","authors_text":"C.-R. Liu, C.-S. Pai, F.-S. Chang, K.-Y. Hsiang, M.-H. Lee, S.-M. Wang, Y.-T.
