title = "Enhanced stabilization of photo-induced Helfrich deformation by doping bent-dimers in cholesteric liquid crystals",
abstract = "In this study, the bent dimers were added in the azobenzene chiral doped cholesteric liquid crystals. The photoisomerization of azo-chiral material can induce a change in pitch and eventually lead to the occurrence of Helfrich deformation. Experimental results show that the photoinduced microgrid structure can be significantly stabilized by adding bent dimers and simultaneously applying a low voltage below the threshold of electric-induced Helfrich deformation. Furthermore, the spacing of the resulting meshed microgrids can be tuned by dimer concentration or applied voltage, revealing its potential for multiparameter controllable optical diffraction devices.",
