Unveiling molecular alignment, dielectric and electrical conductivity of an unaligned 4-octyl-4′-cyanobiphenyl liquid crystal doped with carbon dots

We report the achievement of vertical alignment in the smectic A (SmA) and nematic (N) phases of a 4-octyl-4′-cyanobiphenyl (8CB) LC doped with carbon dots (CDs, ∼2.8±0.72 nm) at concentrations ≤ 0.3 wt%. The composites were filled in indium tin oxide (ITO) sample cells without alignment layer (i.e....
