The tunability of the polarization state of light-emitting diodes (LEDs) based on conventional semiconductors is usually limited. Here, the authors report the realization of mid-infrared LEDs based on a Weyl semiconductor, layered Te, showing the electrical tunability of the degree of linear polarization of the emitted light from ~100% to 36%.
