Figure S1. Investigation of the molecular orientation angles as a function of a transverse position (pitch) of the fabricated CDW. POM observation with 546 nm light source (left), the calculated orientation angle in a transverse position (right, solid black line), and the theoretical angle of a cycloidal molecular orientation (right, dashed red line). White crossed arrows show the direction of polarizers, and a yellow arrow depicts the light scanning direction. Here the angles was simply calculated by the equation: T(%)=sin^2⁡〖(πR/λ)〗 sin^2⁡2θ where λ represents the wavelength of light (546 nm) used for the observation with polarized optical microscope, R represents the retardation of the fabricated film (332 nm) evaluated with a Berek compensator, T at each wavelength represents the transmittance of light passing through both a film and crossed polarizers of POM. The transmittance was calculated by using the image analyzing software (Image J).
