Intergrowth ferroelectric semiconductors, owing to their intrinsic strong spontaneous polarization electric fields, can continuously and effectively facilitate the separation and migration of charge ...

A new device for rotating the polarization of terahertz radiation has been created by accident by researchers in the US. While practical applications remain unclear, the discovery could boost the ...

For example, by adding or dropping a particular color, or wavelength, of light traveling in an optical fiber, scientists can control the amount of information carried by the fiber. By altering the ...
