Electronic devices usually rely on the charge or spin of electrons to encode information. A less exploited route is to manipulate the valley quantum number of electrons. It is now shown that the generation, macroscopic transport and detection of valley-polarized electrons in bulk diamond can be achieved with a relaxation time of 300 ns at 77 K, forming a basis for valleytronic devices.
