Abstract

L'invention concerne un dispositif de production d'onde de surface élastique. Selon l'invention, il comprend un feuilletage composé d'une couche semi-conductrice S, d'une couche d'un matériau piézoélectrique I, et d'une pellicule protectrice I' interposée entre elles; une première électrode M1 est placée sur une surface du matériau piézoélectrique pour application d'une tension continue de polarisation et fournir une puissance de pompage, et une seconde électrode M 2 est placée sur une surface de la couche semi-conductrice pour un contact ohmique avec elle. L'invention s'applique notamment à la production d'amplificateurs.Disclosed is an elastic surface wave generating device. According to the invention, it comprises a lamination composed of a semiconductor layer S, a layer of a piezoelectric material I, and a protective film I 'interposed between them; a first electrode M1 is placed on a surface of the piezoelectric material for applying a DC bias voltage and providing pumping power, and a second electrode M 2 is placed on a surface of the semiconductor layer for ohmic contact with she. The invention applies in particular to the production of amplifiers.
