Currently, the direction of integrated photoelectronics is actively developing, dedicated to the creation of UV photodetectors. In this regard, photosensitive acoustoelectronic amplifiers to incident UV radiation can compete with classical photodetectors, such as photodiodes. The relevance of studying the interaction of UV radiation with charge carriers in structures with surfactants is due to the possibility of creating on its base thermostable sensors and radiometers of the UV range.
