Abstract
We demonstrate a new successful technique for inducing a monodomain in blue phase (BP) liquid crystals (BPLCs). By application of an AC voltage during the cooling or heating of the material into the BP temperature range, a fairly homogeneous BP area was obtained, compared to the case without voltage. We determined that applying a voltage of 3.3V/mu m was very effective in terms of obtaining a monodomain: for four of the seven different applied cooling/heating rates an area ratio of more than 99% was obtained for one particular BP orientation. This study describes a successful and replicable technique to make a BPLC monodomain, which is important for the development of BPLCs and other applications.
