New Application Note Describes Atomic Force Microscopy Tools for Nanoscale Electrical Characterization

Oxford Instruments Asylum Research announces its new application note describing atomic force microscopy (AFM) tools for nanoelectrical characterization. The application note discusses the most recent nanoelectrical characterization techniques, as well as the benefits and exclusive modes that the Asylum Research Cypher™ and MFP-3D™ AFMs offer. Researchers will learn more about evaluating local electrical properties, including current, surface charge and potential, dielectric breakdown, conductivity, and permittivity.

Not only do the dimensions of silicon-based devices keep shrinking to a few nanometers, but also next- generation processes with nanoscale components like nanotubes, graphene, and molecular building blocks are emerging. Understanding physical processes that control electrical behavior increasingly

requires AFM measurements on smaller length scales,” said Keith Jones, Asylum Research Applications Scientist, specializing in electrical characterization. “This application note is a great reference for scientists new to AFM as well as those currently working in the field.”

Asylum Research AFMs are being used by leading researchers around the globe for characterizing nanoelectrical properties. A variety of their publications can be found at:
