Nominator's project description

Dr. Siegrist is well known internationally for his outstanding research in materials science. He has made important contributions to the field of high Tc superconductors, C60 and RxC60 intercalated phases, intermetallic systems such as the rare-earth transition-metal boro-carbides, and more recently in organic semiconductors based on small molecule solids. During his stay in Germany, he intends to study structure property relationships in phase-change materials with applications in novel information storage systems.
