It is based on the application of a strain field, within the sample volume, which tends to align the molecules all towards a common direction. The study was carried out in samples of 4-decyl-4′-cyanobiphenyl (10CB), 4-octyl-4′-cyanobiphenyl (8CB) and n-hexyl-4′-n-pentyloxy biphenyl-4-carboxylate (65OBC) LCs, and the alignment efficiency was monitored by polarisation microscopy observations and by thermal diffusivity measurements.Keywords: phase transitionsphotopyroelectric calorimetrythermal diffusivityRead More
