Argonne Weyl Semimetal (IMAGE) DOE/Argonne National Laboratory Caption An electron incident on a Weyl semimetal from a normal metal is transmitted into specific states in the Weyl semimetal along with a reflection that conserves momentum, energy, and spin. A net spin current with no net flow of electrons can give rise to a charge current in the Weyl semimetal.
