Top two panels show a 2D slice of a gallium arsenide layer with electron position shown in yellow and the direction of their spin shown as red arrows for low (left panel) and high (right panel) temperature. Once the electrons are hot enough, they evaporate out of local traps (bottom panels) and homogeneously distribute throughout the material, evenly spreading the spin.. Building Blocks .
