Electron Gas
Caption:
This is an image of electrons as they move within a nearly two-dimensional (flat) structure made of Ga, As, and Al atoms. In nature, most electrons exist as parts of atoms; in this image, they are flowing free in a low-temperature electron gas. A strong magnetic field created the flowing pattern, a result of the quantum Hall effect. A scanned probe microscope, a research tool that can observe and manipulate objects down to the scale of a single atom, took the image.
This project was supported by a grant from the National Science Foundation.
