ACTIVE ACOUSTIC DEVICES.
Abstract
Investigations of suitable heat sink material needed for CW operation resulted in the development of a BeOloaded epoxy with a thermal conductivity of 1.6 BTU/HrFt-degrees F. This appears compatible with the requirements as previously determined. The open-tube or dynamic technique was determined to be the most feasible for the epitaxial growth of CdS transducers. Theoretical and experimental investigations of the vacuum deposition of CdS resulted in films with resistivity values ranging from 300 ohm-cm to 7 X 10 to the 6th power ohm-cm. Good quality CdS crystals with high mobility and intermediate resistivity levels were obtained by annealing in a sulphur atmosphere. Investigation of the properties of zinc oxide crystals were initiated. (Author)
