Question

How is probe microscopy, and in particular AFM, a useful tool for molecular electronics? Please explain it in a paragraph

Answer 1

In AFM, it captures precise images by continuously moving a nanometer sized tip across the surface of the image

In AFM the probe makes a direct contact with the surface or calculates the initiatory chemical bonding

The tip in AFM touches the surface gently

AFM resolution is far better than the STM. hence AFM is widely used in nano-technology

the Atomic Force Microscope is applicable to both conductors and insulators.

The AFM can be applied with liquid and gas environments

AFM has several advantages .the AFM provides a three-dimensional surface profile analysis . moreover, samples scanned by AFM do not require any special treatments (such as metal/carbon coatings) which can change or damage the sample. atomic force microscopy modes can work effectively well in ambient air or even a liquid environment. This enables to study biological macromolecules and even living organisms.
