✦ Synopsis

The transient high-field conductivity of a simple model of polar semiconductors is studied. In this model it is assumed that the only possible scattering mechanisms is the emission of longitudinal optical (LO) phonons. The time-dependent Boltzmann equation is solved analytically. The behavior of the distribution function is shown for a short period of time after the electric field is applied. *Work performed in the framework of the joint project ESIS (electronic structure in solids) of the University of Antwerp and the University of Liege. tFor more information on polar interactions see Ref. 4.

## Abstract The ac conductivity is calculated taking into account combined scattering by polar optical modes and ionized impurities. For small electric fields oscillating in time the Boltz‐mann equation is solved. Good agreement between Drude's simple theory and our calculation is obtained in the l
