AFM for Organic Semiconductors & Polymers

Organic semiconductors, conducting polymers and self-assembled monolayers are soft and easily damaged by a contact tip. Soft ResiScope™ maps their conductivity with controlled force, HD-KFM™ III the surface potential, and Soft MEKA the mechanical contrast of blends.
