The possibility of controlling the growth of the metal nanoclusters by changing the morphological featu

## Abstract The mechanical properties of 2D honeycombβstructured polymer sheets (HSPS) are investigated with respect to the polar angle at large deformation. The tensile force fluctuates as an undamped negative sinusoidal wave with a periodicity of 15Β°. The amplitude of the fluctuation is proportio
quenching to room temperature. As a result, the polarization bandwidth was found to increase by a factor of 2.4 over what was expected of a constant-pitch film. The increased bandwidth was attributed to a pitch gradient resulting from photoinduced racemization of the chiral dopant at the irradiated
