Electrons Embedded in Atomic Lattice (image) Goethe University Frankfurt Caption Electrons embedded in the atomic lattice -- the components of a solid are shown. The mutual repulsion of the electrons prevents them from coming into close contact. This impedes the electron flow and the system can become an insulator.
