“…Theoretically the off-axis angle of maximum amplification increases with increasing voltage until it saturates a t 30°, because the electromechanical coupling factor in CdSe has a maximum a t 30". I n practice, however, acoustic scattering losses a t the crystal side faces reduce the saturation value of the off-axis angle somewhat [4]. As a consequence of the existence of an angular distribution of amplified off-axis waves the resonances occur-ring in Fig.2 are broader than the theoretical predictions; in the theory a delta-function off-axis distribution was assumed.…”

An investigation is made of the electro-acoustic current saturation, electro-acoustic current noise, and eIectro-acoustic effects in the ac impedance for a single crystal of hexagonal n-type CdSe. The electric field is applied along the c-axis. The experimental data are interpreted in terms of a previously published theory. It is concluded that the experimental data for CdSe are described very well by this theory. The experimental results for CdSe are similar to previously published results for CdS.Electro-akustische Stromsiittigung, elektro-akustisches Stromrauschen und elektro-akustische Effekte in der elektrischen Impedanz werden in einem hexagonalen n-Typ CdSe-Kristall untersucht. Die experimentellen Daten werden mit Hilfe einer fruher veroffentlichten Theorie interpretiert. Die experimentellen Ergebnisse fur CdSe stimmen sehr gut iiberein mit dieser Theorie. Die Ergebnisse fur CdSe sind fruher veroffentlichten Ergebnissen fur CdS Lhnlich.

“…Recently we reported an extended set of experimental data on electro-acoustic current saturation [3,4], electro-acoustic current noise [ 5 ] , and electro-acoustic effects in the ac impedance [3,4J for single crystals of hexagonal n-type CdS. In the samples the amplified acoustic flux originated from the thermal background.…”
