ABSTRACT:
Low reflectivity electrodes (2, 7) are provided on semiconductive and piezoelectric substrates (1, 6) including a layer (3, 9) of gold-germanium mixture and a layer (5, 8) of raw gold, or only a gold-germanium mixture (10), the total germanium content of the electrode comprising approximately 2%-3% of the total gold and germanium content of the electrode, and the thickness of the electrode being on the order of 1% of the acoustic wavelength.
