The possible application of crystals from the sillenite group (Bi12SiO20, Bi12GeO20, Bi12TiO20) to detect radiation in the terahertz (near infrared) range is considered. Photosensitivity for the spectral range of 3–30 μm is provided by application of the shallow traps located near the bottom of the conduction band. The crystal sections are determined, at which the electro-optical and piezoelectric effects can be used to develop a voltage on the surface electrodes. The electrodes made in the form of an interdigital transducer or a spiral complement the device with new functional capabilities.
