Because several ACerS members are directly or indirectly involved with LED research and development, and because I am doing some remodeling at my house, I figured that now would be a good time to investigate what reasonable LED options are available for residential lighting. I was even willing to fork over some extra cash for the inevitable …

JAIST researchers have developed three types of silicon ink:  aB-doped p-type, an i-type (intrinsic) and a P-doped type.Credit T. Shimoda; JAIST. Typically, photovoltaic units composed of thin-film silicon materials do not involve amorphous or single-crystalline silicon, and making thin-films with poly-silicon is still a frontier field (see previous post). But researchers at the Japan Advanced …

We’ve reported in the past on the incredible magnification powers of scanning electron microscopes. An SEM is a type of electron microscope that images the sample surface by scanning it with a high-energy beam of electrons. The electrons interact with the atoms that make up the sample producing signals that contain information about the sample’s …

A pink object under the cloak becomes invisible. Credit: SMART Center. Last week I mentioned that someone has found a new, cheap way to optically “hide” objects (other than the metamaterials route). Via Gizmag, I heard about the the work of two groups who, in parallel, are using calcite crystals to make objects seem to disappear — …

Credit: Penn State Isn’t there a law or something that prohibits using metamaterials for something other than invisibility cloaks?* According to Douglas H. Werner, professor of electrical engineering at Penn State, creating a new type of antenna is one of the first practical implementations of electromagnetic metamaterials that makes a real world device better. “These …
