Abstract

We have studied liquid crystal (LC) aligning capabilities for homeotropic alignment and the control of tilt angles on the thin film by electron beam evaporation method. A high tilt angle of about was obtained, and also the suitable tilt angle of the NLC on the thin film at thickness with e-beam evaporation can be achieved. The uniform LC alignment on the thin film surfaces with electron beam evaporation can be achieved. It is considerated that the LC alignment on the thin film by electron beam evaporation is attributed to elastic interaction between LC molecules and micro-grooves at the thin film surface created by evaporation.
