Abstract
The angular dependencies of the linear bulk photovoltaic effect (BPE) under linearly polarized x-ray synchrotron radiation in LiNb: Fe, Si: Pr, and Si have been revealed. This is the first observation of the tensorial properties of BPE under polarized x rays, which reveals giant values of the components of the photovoltaic tensor . The values of at 850 eV are 3-6 orders of magnitude higher than the corresponding values for the optical region. The present results may also explain the origin of x-ray photorefractive effect previously observed in LiNb: Fe.
