Observation of Alignments in Mixtures of Cyanobiphenyl Liquid Crystals on Molybdenum Disulfide Substrate with STM

Abstract

We investigated mixture alignments in cyanobiphenyl liquid crystals. In present study, we observed monolayer alignments in liquid crystal mixtures (10CB-9CB and 12CB-11CB) on molybdenum disulfide (MoS₂) using STM. Two kinds of specific alignments are observed in each mixture such as a unit consisting of three molecules and a unit consisting of five molecules in single row structures. All the alignments have the common feature such that different kinds of molecules align antiparallel each other in a single row.
