Zoom into a Pencil Line of Graphene with an Atomic Force Microscope (AFM) - Illustration

This poster feature zoomed images of a pencil line down to the molecular level.

DESCRIPTION

This illustration shows how an Atomic Force Microscope (AFM) is used to image a line of graphene made by a pencil. The scale spans ten orders of magnitude, from the microscope and pencil to the atoms that compose the scanning probe and pencil line. As the viewer zooms into the line, graphite flakes, and eventually a single layer of graphene, become visible. On the AFM, a silicon cantilever with a sharp atomic tip and a laser with a photodiode measure the up and down motion as the probe maps out the graphene sample.

OBJECTIVES

NANO CONTENT MAP

Nanometer-sized things are very small, and often behave differently than larger things do.

Scientists and engineers have formed the interdisciplinary field of nanotechnology by investigating properties and manipulating matter at the nanoscale.
