Abstract :
The threshold behaviour of cholesteric to nematic phase-change cells with homogeneous and homeotropic surface alignment is compared. The former raises, the latter lowers, the threshold voltage. Departures from predicted linearity are seen when the cholesteric pitch is comparable with the film thickness.
