| We report on polarization spectra of spontaneous terahertz electroluminescence from uniaxially deformed Ge(Ga). At compressive pressure of about 3±0.3 kbar in the [111] direction, near the impurity breakdown threshold, the linear polarization degree attains ≈80-90% for the main lines of the terahertz emission. |
