In CdS crystals with an N-shaped negative differential conductivity range stationary high field domains adjacent to the electrodes are observed. With increasing applied voltage these steplike domains increase in width staying attached to the cathode until they fill the entire crystal, then a still higher field domain is formed at the anode and increases in width. These domains can be explained within an earlier published theory and allow the determination of electron densities at the cathode-CdS boundary, and in the field quenched region. The analysis of these stationary domains presents a new tool for work function metal semiconductor investigations. Author
