Magnetically steered liquid crystal-nanotube switch

摘要: Liquid crystals LCsRef. 1 are spontaneously selforganized anisotropic fluids. They combine fluidity with the anisotropy of physical parameters and elasticity observed for solids. The simplest LC phases is nematic, which exhibits solely orientational order long molecular axes along a preferred direction called director. displays LCDs based on nematics by now mature technology utilized in wide range applications from simple black white pocket calculators to high-end full color television screens. All these electric Freedericksz transition, collective reorientation director an applied field positive dielectric anisotropy. Carbon nanotubes 2 also highly materials. exhibit large elastic modulus conductivity tube axis, while being flexible nonconductive perpendicular direction. Proposed nanoelectronics 3 biochemical sensors. 4 It lies at hand two modern materials design novel nondisplay devices LC-nanotube dispersions. has recently been shown that through
