Microphotographs of a MWNT-doped TN cell in the on state with field intensities of (a) , (b) and (c) . The spots at 0 V are due to ball spacers.
Measured voltage-dependent (a) capacitance and (b) transmittance curves by applying ac voltage.
Measured hysterisis curves in voltage-dependent (a) capacitance and (b) transmittance by applying dc voltage.
The optimized geometries of (a) 3,4,5-trifluorophenyl LC molecule, and those interacting with (b) open CNT and (c) H-functionalized CNT. The dashed lines in (b) and (c) are the shortest bond lengths of hydrogen atom at LC molecule and carbon atom at CNT.
Microphotographs of a MWNT-doped vertically aligned LC cell at (a) 0 V, (b) 120 V, and (c) 0 V released just after applying 120 V.
