“…The present work which is a continuation of a series of woks devoted to TR [1,2,5,[13][14][15][16][17] is completely theoretical. The results of the first works on the existence of the TR effect were repeatedly discussed both at scientific conferences and during private discussions.…”

In the transverse electric and magnetic field, in Hall regime the low-temperature impurity breakdown (IB) under transverse runway (TR) conditions is considered. The effect of the increase in the compensation degree on the IB and TR applied electric field ratio is studied at different values of the magnetic field. It is shown, that with the increase in the magnetic field critical electric fields relevant to IB and TR must tend to each other, while at the fixed magnetic field the IB critical field approaches the TR threshold field with the increase in the compensation degree. The obtained results are at variance with the well-known fact that the applied breakdown field tends to infinity at C 0 ! 1, that is to say when the concentration of free charge cariers tends to zero; in asymptotics the applied breakdown and threshold fields merge.

The transverse runaway (TR) is a phenomenon whereby for a certain combination of energy and momentum scattering mechanisms of hot electrons, and for a certain threshold of the applied electric field, the internal (total) field tends to infinity. In this work, the effect of the magnetic field on the transverse runaway threshold is considered. It is shown that with increasing magnetic field, the applied critical electric fields relevant to TR decrease. The obtained results are important for practical applications of the TR effect as well as for the investigation of possible nonlinear oscillations that may occur near the TR threshold.
