Ultrafast Electric Switching of Brookite TiO2 Nanorods with a Permanent Dipole Moment at High Concentrations

Advanced Materials Interfaces
Transient electric birefringence measurements are used to show that brookite titania nanorods dispersed in the apolar liquid butylbenzene possess a large permanent dipole moment of 516 debye (rod length: 39 nm, diameter: 4.1 nm). This dipole moment makes
