Research in electronic materials and devices in electrical engineering at Princeton covers a very broad range of topics. We are creating nanotechnologies for electronics, optics, optoelectronics, magnetics, and biology. We are developing new materials and device structures for manipulating and storing quantum bits of information for quantum computers. We study novel molecular semiconductors for organic electronics, with huge potential for solar energy conversion and large-scale flexible electronics for e-textiles. We also use photons produced by unique quantum cascade lasers to develop new methods for health and environmental monitoring. Researchers in electronic materials and devices enjoy making micro and nanostructures with new functions, understanding their physics, and bringing them to applications. All along, they also like playing high-level detective because the world of experiments is full of surprises!
