QMC Researchers Develop Infrared Torsional Force Microscopy

Resolving nanoscale light-matter interactions requires both high spatial resolution and anisotropic sensitivity to in-plane and out-of-plane optical responses. A QMC team lead by Min Ouyang has introduced torsional force microscopy-infrared microscopy, a new optical imaging technique that combines cantilever torsional dynamics with a nonlinear frequency-mixing scheme to map both in-plane and out-of-plane photothermal signals.
