Functional materials and energy materials display a range of impressive multi-field coupling effect, such as the coupling between strain, strain gradient, electric, magnetic and thermal field etc. The extreme sensitivity of this coupling effect to material composition, structure and external stimuli offers possibilities for designing new devices. By combining first-principles theory and neutron/synchrotron techniques, we investigated a novel coupling effect between strain gradient and electric polarization (flexoelectricity) and revealed atomic vibrations play a critical role in the multi-field coupling effect in the functional materials and energy materials.
