Abstract
Abstract:
The structural, physical, and electronic properties of ferroelectric materials have interesting implications for future devices. Of relevance is the ability to control nanoscale domains at the mesoscale using conjugate fields. CsBiNb2O7 2D flakes is one such ferroelectric material exhibiting unit cell to sub nm thick ferroelectric domains [1]. Here we utilize Bragg Coherent diffraction imaging to probe the evolution and mobility of ferroelectric and elastic domains [2] in CsBiNb2O7 under an external electric field. We shall discuss our BCDI results and implications in phase transitions.
