PROCESSES OF FORMATION OF SUPERLATTICES IN ENSEMBLES OF LC DROPLETS

Abstract

The processes of formation of lattices in cholesteric LC layers from drop domains («bubble domain») in electric fields are studied in this paper. The LC layers were subjected to tension. At a certain thickness of the LC layer, the so-called “cholesteric fingers” were formed, the system of which, with an increase in the dimensionless parameter C = d/P0 (d is the layer thickness, P0 is the equilibrium pitch of the cholesteric LC), decomposed into separate droplet domains. By varying the magnitude of the electric field, one can control both the size of these domains and the density of their packings.
