Visualizing and Probing the NanoworldThe nanometer-scale mechanical, physical, and chemical properties of surfaces and interfaces - explored and quantified by local probe-based techniques
What we doThe properties of materials are determined by the nature of the interactions between the atoms that form the material. Site-specific measurements of surface forces help us to understand their atomistic origins and, ultimately, to tailor them within certain limits. Our group specializes in using local probes, in particular advanced atomic force microscopy-based techniques and related scanning probe methods that are continuously further developed in our lab and nanoindentation-based techniques to quantify and map surface forces, interaction energies, mechanical properties such as hardness and Young's modulus, and other parameters such as tunneling currents and charge distributions with high resolution. Results obtained from those measurements are then complemented with data obtained using complementary approaches including various microscopy/spectroscopy techniques and mechanical/thermal testing. Current projects address problems in materials science, surface physics, catalysis, and nanomechanics. Send mail to udo.schwarz@yale.edu with questions or comments about this web site.
