Objectives

This course aims to provide an in-depth knowledge of the atomic force microscopy experimental technique suitable for studying the surface properties of new materials at the nanometric scale.
The course includes: theoretical lessons, for the study of the basic theoretical principles and practical lessons in the laboratory to deepen the structural characterization of materials.

Contents

• Theoretical principles of operation of atomic force microscopy
• Methods of analysis
• Instrument set up and sample preparation
• Applications in the environmental field

Extended Syllabus

• Theoretical operating principles:
