    • If the compound exhibits the uniaxial Sm-A phase, the indices of refraction and the layer spacing can be measured by pulling a series of films in the Sm-A phase. Then N of any film can be determined. See P.M. Johnson, D.A. Olson, S. Pankratz, Ch. Bahr, J.W. Goodby, and C.C. Huang, Phys. Rev. E 62, 8106 (2000).

    • note
    • The quality of the data obtained from the thin films is affected by the fact that there was a electroconvection flow of the material in the presence of E as was also reported in Ref. [8]. Nonetheless, as shown in Figs. 2(a) and 2(c), it is still possible to obtain conclusive data even under such conditions.

    • If the tilt orientations of layers are not uniform along the layer normal, flexoelectric polarization exists. See R.B. Meyer, Phys. Rev. Lett. 22, 918 (1969). We cannot distinguish the flexoelectric polarization from the longitudinal polarization.

    • 2 phase [8]. However, such a structure implies that in even- (odd-) layer free-standing films, there should be a net polarization in (perpendicular to) the tilt plane [18]. Thus, the observation and proposal of Ref. [8] contradict each other.
