Graphene: Surface Acoustic Wave Driven Light Shutters Using Polymer-Dispersed Liquid Crystals (Adv. Mater. 14/2011)

The cover shows a surface acoustic‐wave driven light shutter formed from a polymer‐dispersed liquid crystal (PDLC) film. In regions without surface acoustic waves (SAWs) the LC molecules in the droplets show a radial alignment, while within the SAW working region, the LC molecules show an alignment...

Description
Summary:The cover shows a surface acoustic‐wave driven light shutter formed from a polymer‐dispersed liquid crystal (PDLC) film. In regions without surface acoustic waves (SAWs) the LC molecules in the droplets show a radial alignment, while within the SAW working region, the LC molecules show an alignment perpendicular to the substrate. With further optimization, this PDLC‐based light shutter, reported on p. 1656 by Tony Jun Huang and co‐workers, could possess advantages such as low power consumption, high throughput, and excellent optical properties.
