Microscopic look of the surface of gallium arsenide. 

This microscopic image of the surface of gallium arsenide (GaAs) shows how the arrangement of atoms on the GaAs surface affects its electric field. The image illustrates the manipulation of individual atoms to allow for very precise tuning of the characteristics of GaAs-based transistors.
