Nanocomposite Spiral (IMAGE) Technical University of Munich (TUM) Caption Similar to carbon, silicon forms two dimensional networks that are only one atomic layer thick. Like graphene these layers possess extraordinary optoelectrical properties. Embedding them in a polymer, scientists at the Technical University of Munich (TUM) have developed a stable composite material which can be processed with standard polymer technology.
