Temperature dependence of the critical sample thickness at which a cholesteric structure unwinds spontaneously between surfaces with homeotropic anchoring are presented for some dielectrically negative chiral nematic mixtures. The results obtained are pertinent to the application of the nematic‐cholesteric phase change‐effect in liquid crystal devices.
