FUNDAMENTALS OF ATOMIC FORCE MICROSCOPY, PART 1
A free two-part series of online courses covering the principles and practice of atomic force microscopy
Professors Arvind Raman and Ron Reifenberger have developed two web-based courses in response to enthusiastic feedback received for video lectures posted on nanoHUB.org that discussed all aspects of scanning probe microscopy (SPM). The original video lectures have attracted over 7,000 viewers worldwide. The course content has been refined and condensed from the original full-semester course offered at Purdue University beginning in 2009 into two, five-week online courses. The courses develop a unified framework for understanding the multifaceted aspects of atomic force microscopy.
The course material of Fundamentals of Atomic Force Microscopy, Part 1: Fundamental Aspects of AFM is available as a free self-paced class taken online.
Recommended reading material, Fundamentals of Atomic Force Microscopy, Part I: Foundations by Professor Ronald Reifenberger is now available via World Scientific Publishing Company.
Scientific Overview Video
The atomic force microscope (AFM) is a key enabler of nanotechnology, and a proper understanding of how this instrument operates requires a broad-based background in many disciplines. Few users of AFM have the opportunity or resources to rapidly acquire the interdisciplinary knowledge that allows an intelligent operation of this instrument. This focused, in-depth course solves this problem by presenting a unified discussion of the fundamentals of atomic force microscopy. By registering for this course, students will be exposed to the knowledge base required to understand how an AFM operates.
Fundamentals of Atomic Force Microscopy, Part 1: Fundamental Aspects of AFM is designed to develop many key concepts – both theoretical and experimental – which allow a better understanding of the principles underlying the AFM.
Who Should Take the Courses
As the use of AFM expands, there must be a greater understanding of AFM techniques at all levels to better appreciate how AFM can be used for any particular application. Those requiring more than an entry-level understanding of AFM might include:
- Graduate students beginning a research topic involving AFM
- Continuing-education professionals
- Scientists and engineers involved in commercial or industrial R&D
The online course is intended to be broadly accessible to beginning graduate students in any branch of science or engineering.
Fundamentals of Atomic Force Microscopy, Part 1: Fundamental Aspects of AFM requires a basic familiarity with topics usually covered in a two-semester college course in introductory physics. Selected topics from upper-division undergraduate courses in electricity and magnetism, thermodynamics, and quantum will be reviewed when required. A working knowledge of both integral and differential calculus is assumed. A basic understanding of electronic circuit concepts will be helpful.
