Observation of domain patterns induced by ultrasound pulses in a nematic liquid-crystal film.
The homeotropically aligned nematic liquid-crystal layer with a free circular edge is studied. Domain patterns induced by high-frequency ultrasound pulses are observed for the first time to our knowledge. The pattern changes for different incident angles of the ultrasound and can be enhanced by a quasi-static electric field.
