In July, 2012, the UW-MRSEC hosted graduate students from the University of Puerto Rico Mayaguez. While in Madison, Wisconsin the students performed their Science on Wheels (Ciencias en Ruedas) show at the Wisconsin Institutes for Discovery on the UW-Madison campus.
Manipulating the topology of iso-frequency surface provides a new approach for control of light-matter interaction. This is demonstrated using anisotropic metamaterials consisting of metal-dielectric layers.
Metals have many disadvantages as components of optical metamaterials. Semiconductor-based materials overcome these problems. We build a high performance, all-semiconductor-based metamaterial by replacing metal with heavily-doped zinc oxide and demonstrate negative refraction in this near-infrared metamaterial. This demonstration
LCMRC researchers have developed a method for manipulating particles by light without touching them by using liquid crystals as a light-controlled host fluid.
Center researchers are collaborating with spin-off Displaytech (now part of Micron Technologies) to develop ferroelectric liquid crystal (FLC) materials for application in picoprojectors. The high-quality time sequential color and high brightness enabled by FLC switching speed, and high fill fact
In a photovoltaic cell, an incident photon creates an electron (black circle in top sketch) and a hole (open circle).
