In

electric polarization effects. The beam-like structure/element

carbon nanotubes
(CNTs) are typical ones for electrostatic deflections.

Mechanisms of electric deflection due to

electric polarization
can be understood as follows:

As shown in Fig.2, when a material is brought into an

molecular dipole moment and the electric field results an induced torque (T). Then this torque
tends to align the beam toward the direction of field.

In case of a cantilevered CNT (Fig. 1), it would be bent to the field direction. Meanwhile, the electrically induced

carbon nanotubes.[8]
