- John C. and Helen F. Franklin Professor of Applied Physics
Spaepen conducts research in the following areas:
Colloidal systems as analog computers for the study of defects and deformation of crystals and glasses (with D. Weitz).
Amorphous materials (metals, semiconductors, polymers): structure, formation, stability, mechanical properties, atomic transport (viscosity, diffusivity, structural relaxation, crystallization).
Properties of interfaces: crystal/melt, amorphous/crystalline semiconductor, grain boundaries, grain growth, interface tension, interface stress, and interface stiffness.
Thin films and multilayers: preparation, stability, mechanical properties. General effects of size scale on mechanical properties.
