ABSTRACT:
The invention relates to piezoelectric devices employing a piezoelectric layer deposited on a substrate devoid of piezoelectric properties at ambient temperature. The device in accordance with the invention is provided with a piezoelectric layer made from a mono-atomic crystalline material, namely selenium. The invention is applicable to the excitation of surface elastic waves along non-piezoelectric substrates, to the excitation of bulk elastic waves and to the detection of infrared radiations.
