Bimodal AFM Tutorial at the Multifrequency AFM Conference, Madrid, Spain March 13

The need for higher compositional resolution and sensitivity has led to exploration of imaging with higher harmonics and/or flexural or torsional cantilever modes. More recently, the AFM is experiencing the evolution from single to multi-frequency excitation and detection schemes.

The Bimodal AFM Tutorial, held on the afternoon of March 13, 2011 in conjunction with the 3rd Multifrequency AFM Conference, will cover a variety of topics by leading researchers in the field iincluding cantilever physics, materials contrast, bimodal imaging theory, simulation with VEDA, and future directions of the technique. Techniques will be demonstrated on AFM instrumentation.

The tutorial is open to all attendees of the Multifrequency AFM Conference. Class size is limited to 15 people. Registration can be found at: http://www.imm.cnm.csic.es/spm/multifrequency/home.html
