It is shown that in n‐type material with negative differential conductivity due to field quenching, stationary cathode‐ or anode‐adjacent high‐field domains occur dependent on electron density at the cathode and applied voltage. Cathode‐adjacent high‐field domains can be observed only with a blocking cathode. Anode‐adjacent high‐field domains occur with a slightly blocking cathode at applied voltages above the range at which cathode‐adjacent domains are observed or as the only domain type possible with an injecting cathode. With different cathode metals evaporated onto the same CdS:Ag, Al crystal the electron density in the conduction band n 1 ( E ) for space charge free conditions has been determined as a function of the actual field between 0 and 240 kV/cm.
