Abstract
An acoustical-electronic component operating with acoustical surface waves, includes a piezoelectric substrate in which an acoustical surface wave is guided and enters into interaction with an electron system disposed on the substrate in the travel path of the acoustical surface wave. The electron system is constructed as an electron channel that is tunable in its electrical conductivity by field effect. A tunable delay line, a resonator and a semiconductor sensor use the component.
