The disclosure is directed to a method and a device for delaying an electrical signal, the method and device being useable in various signal processing applications. A buried channel is formed by disposing a portion of a layer of piezoelectric semiconductor material between confining layers. A surface acoustic wave is established in the piezoelectric semiconductor material. Majority carriers are depleted from the channel, and an electrical signal is injected into the channel. A delayed version of the electrical signal, which had been carried along by the surface acoustic wave, can then be extracted from the channel.
