ملخص

We report observations on a chiral nematic liquid crystal confined in a plane cell treated for homeotropic alignment. The characteristics of the specimen investigated are such that at room temperature a uniform homeotropic alignment is observed and at higher temperatures the material displays the helical structure. It is observed that the changeover between homeotropic and helical textures does not occur at one single threshold. There are two thresholds, between which there is an intermediate texture where small circular domains are observed. These domains may be regarded as circular analogues of the plane solitons predicted by previous authors.
