Threshold switching and microwave-induced spontaneous emission in p-Ge in a static magnetic field
Brazis R. S., Mironas A. S.
Experiments on the impurity breakdown of />-Ge in a circularly polarized electric field Ε and a static magnetic field B01E reveal a switching accompanied by the formation of an anomalously large number of light holes. This switching occurs after a threshold value ofE/B0 is reached. A magnetized hole plasma radiates photons at wavelengths λ ~ 100 μτη.
