Metal surface,helium spin imaging. This imaging technique shows the ions and electrons of a metal surface at the quantum level. Known as the helium-3 (He-3) spin-echo technique,a beam of polarised He-3 atoms is fired towards the surface of the metal so that the energy changes during scattering can be measured. This technique can record measurements on the sub-nanometre and nanosecond scales. The results are built up digitally to reveal a three-dimensional image of the surface. Here,the metal is seen as a lattice of positive metal ions (blue) in a sea of electrons (red) | |
