• The motion of a plasma density perturbation in n-InSb at 77°K was investigated experimentaly over a wide range of applied electric fields, from the ohmic to the breakdown region. Below breakdown, as is well known, a density perturbation travels to the cathode, in the same direction as that of holes. When the electric field exceeds the critical field for the breakdown, the velocity of the perturbation reaches the maximum value of 4.7×10^5 cm/sec. As the field is increased further, the velocity decreases through zero, and reverses its direction from that for holes to that for electrons. At the highest field used the velosity reached about -5×10^5 cm/sec. These observation agrees well with the theory of the plasma density velocity and provides good confirmation for the basis of the hot carrier double injection theory, which was previously based on a proposed velosity reversal in n-InSb.
