Self-Assembled Nanoprisms Form Smectic Crystal

Richard Gaughan

Building nanometer-scale devices such as photonic crystals requires assembly techniques of unprecedented accuracy. Developing these techniques can be as difficult as designing the devices and, thus, self-assembly methods — in which the components of nanoscale devices put themselves into the desired configuration — are highly desirable. A new technique creates self-assembled hollow hexagonal nanoprisms that can collect into a smectic phase that could function as a photonic crystal. At the Chinese Academy of Sciences in Beijing, researchers have found that, when zinc meso-tetra (4-pyridyl)...Read full article

    photonic crystals
    Photonic crystals are artificial structures or materials designed to manipulate and control the flow of light in a manner analogous to how semiconductors control the flow of electrons. Photonic crystals are often engineered to have periodic variations in their refractive index, leading to bandgaps that prevent certain wavelengths of light from propagating through the material. These bandgaps are similar in principle to electronic bandgaps in semiconductors. Here are some key points about...
